People are strange... Reading the comments it's like some people didn't watch the same movie. Their complaints are literally the opposite of each other. For example, some say it's not enough like the original trilogy, while others say it's just a regurgitation with nothing new. Some say there isn't enough action, while others say there's too much. Though we didn't necessarily need another one, I still enjoyed it. For those who don't know, and that seems to be most reviewers, Lana Wachowski wrote this due to the death of her parents. Her sister chose not to participate for the same reason. The studio likely greenlit it for the same reason as other late sequels to a successful franchise - they hope to capitalize off of nostalgia. Note there will be spoilers in the rest of my review.
I thought the plot made perfect sense, and I'm not sure why some people didn't get it. Yes, there are things for which you have to suspend your disbelief. HELLLOOO! This is science fiction, which is always a mixed bag. You'll get more actual science than a comic book, but creative license will still be taken. If you want nothing but science fact, stick to nonfiction. Though it wouldn't surprise me if some of the real world theories being explored wouldn't seem just as unbelievable to some reviewers. Personally, I didn't notice anything that was any more fantastic than Terminator, I Robot, Inception, or the original Matrix trilogy. So, where are we now in relation to the end of Revolutions? Basically, though Neo defeated Smith, and the Architect kept his word to end the war, another rogue program saw an opportunity and took control. If you recognize how many programs, particularly the rogues and exiles, behaved like humans, this is perfectly logical. Take down one power hungry dictator and another will rise up and try to fill the void. It's why we don't have world peace. However, this new program, the Analyst, understands human nature a bit better than the Architect and, after a few failed attempts, has created a new Matrix where there are far more blue pill people. Though the red pills are still trying to free people, they're having less and less success. The Analyst leaves IO, which replaced Zion, alone, and the free people live a relatively peaceful and vastly improved life. This was partly made possible by shifting their mindset and learning to work with some of the programs and machines that decided, after Neo ended the war, and due to scarcity of resources that caused them to turn in each other, that they too wanted to be free of the Matrix. The one major hiccup and central part of this movie is that the Analyst somehow managed to save Neo and Trinity, slow their aging, and prolong their life. This is one of those areas where we have to suspend disbelief. And hey, who knows what medical science will be able to do in the future? But the Analyst saved them and then used them as a key component to creating his new Matrix. Neo is back to being Thomas Anderson, but is now a video game designer, with the Matrix being his most successful game. He's been convinced his memories are a delusion, and he's receiving psychiatric treatment. Trinity is married to someone else and has children. Both accept the Matrix as reality and rationalize or ignore any feelings to the contrary. Neo's subconscious is strong, however, and he inadvertently creates a program that leads Bugs, one of the free people still trying to free others, to a new digital Morpheus (the original died), which subsequently leads her to Neo. Neo is rescued, and the rest of the movie is focused on rescuing Trinity. The Analyst, however, is more powerful and has more control than the Architect did, so the first attempt fails. The second attempt is a complex plan that involves Neo distracting the Architect while the rest liberate Trinity's body. There's a bit of science fiction mumbo jumbo explaining how they disconnect her body while she's still in the Matrix. Again, suspend your disbelief and move on. Those are the main points. Remove the sci-fi trappings, and it's a pretty basic plot. Boy who loved and thought he lost girl realizes she's alive and, with the help of some new friends, goes to rescue her. What's difficult about that?
The fact that many of the old characters are gone makes perfect sense, considering it's been 60 years. For that matter, how many characters from the first film survived? Both the 2nd and 3rd films introduced new characters as the story evolved. I actually like the new characters, particularly Bugs. I'd have liked to see more of them, but again, compared to the original trilogy, I didn't see a huge difference. This is Neo and Trinity's story and always has been.
Neo's fight scenes not being quite on par is also quite logical considering both the character and the actor are older and a bit rusty. Neo has been living an action free life in the Matrix for over half a century, and he's not given much time to get his mojo back. If anything, I thought Trinity's sudden resurgence followed by a huge leap stretched credibility. But again, I just accepted it and enjoyed the dose of female empowerment. It wasn't a deal breaker. As for Keanu Reeves, considering he is almost 60, I think he's pretty bad ass. I'd like to see those complaining do better. And while I haven't done any time comparisons, I didn't notice any real change in the level of action. It felt on par with the others, which fyi had a lot of exposition because the studio insisted on it. They didn't think the original scripts would make sense to the audience. But this film has plenty of fighting, bullets flying, vehicles crashing, things exploding, and an added bonus of people being used as projectiles literally going splat on the pavement. What more do people want?
As for those missing, mainly Laurence Fishburn and Hugo Weaving, sure it would have been great to have the original actors, but after almost 20 years that isn't always possible. It's not even always possible with a sequel that closely follows. Usually the audience just has to accept it. At least here we get reasons that fit the story. Smith having a different appearance actually makes sense in regards to convincing Neo his Matrix life is real. And Morpheus is explained well enough. Don't know why the actors didn't return, and unlike some other reviewers, I'm not going to make assumptions to support my own opinions of the film. I will say, regarding Laurence Fishburn, the one comment I did see from him did not lead me to think he didn't want to participate. There are a number of reasons actors don't end up doing a sequel. This is nothing new. The new actors did a good job. They were enough like the originals to make the connection and different enough considering the time that's passed and the fact that they aren't exactly the same characters. They're both programs, one based on a living person and one an upgrade to an older program. So again, the changes make sense within the narrative.
Overall, this felt very much like a continuation of the original story. We can have stories with a satisfying ending, but there's always more we could tell. As Smith tells Neo, stories never really end. For me, the best part of this chapter of the story, and a good reason for it to be told, is seeing Neo and Trinity get their happy ending. I wasn't dissatisfied with their sacrifice in the original ending as it was true to their characters. But it was also the epitome of life isn't fair. After everything they did, after making so many sacrifices, they deserved more. So I'm not unhappy seeing them given a second chance at happily ever after.
