Pros
+ Incredible performances from the Original 6 Avengers
+ Strong Emotional Impact
+ Unexpected Surprises
+ Incredible Direction from the Russo Brothers (Seriously, hats off to these guys who did the impossible)
+ Solid Humor
+ Strong Pacing (except the 1st Act which at some times is a bit slow)
+ Cinematography (Lots of Great Shots that I want to frame them on my wall)
+ Sound Effects & Mixing
+ Alan Silvestri's Best Score
+ Easter Eggs & References from previous MCU movies
+ The Entire 3rd Act
+ Strong Rewatchability
+ Taking Risks on its characters, that ultimately works
+ Amazing payoff for the characters and this universe
Cons
- A Plot Element that set up its rules, but kinda broke them especially in the end. (Overall, I didn't care that much because that element will always have Convoluted Mess in movies that can easily be nitpicked)
In conclusion, this is definitely my favorite MCU movie. This is a thank you letter for the fans who stuck with this franchise for 10+ years and this is their reward. Highly recommend watching more than once because it gets better each viewing.
My score : 9.2/10
