Ignore the other reviews This marks the end of my reliance on amateur movie reviewers in making a decision about whether or not to watch any given movie. Because of them, I almost didn't watch this one. I will say this: Ignore everyone who bagged this film. They don't know what they're talking about. After reading endless 1-star reviews, and even some 9- or-10 star ones, I see that none of them got it right. Of the bad things I might say about this film, the worst would be that the science is just terrible. I don't blame this on the filmmakers directly, rather on the average american being so ignorant of things scientific that the makers know they can get away with almost anything. In large part, I can live with this. The requirement to suspend disbelief is very common for moviegoers, and for a lot of reasons. But, when it comes to science, it is different. A lot of us know pretty much what is possible and what is not. The science in this film failed when it came to scaling everyday big-people's objects to the small world. It just doesn't work. The small world looked just like ours. In order to have fridges, ovens, toasters, televisions, etc. that look exactly like the ones we have, there would have to be massive miniature factories with hordes of miniature robots building these devices from impossibly tiny components. A whole manufacturing economy would have to be in place. I saw no evidence of this. All the little peoples' needs appeared to be provided by big people. None of the reviews I read noted that a shrunken person would necessarily have a very high, squeaky voice. They all sounded exactly like lower-volume big people. Of course, that would ruin the whole film, so best to just ignore it.
Nowhere in the film did I see any reference to shrinking any beings other than humans. Yet, in Norway, we see horses, sheep, dogs, all suitably miniaturized. The first thing that struck me when I saw the miniature yacht in the Norwegian fjord was that the thing was only about 3 feet long at most; the fjord was glassy smooth, but I'm quite sure they're not always like that. The weather can get very nasty, and if it did, a 3-foot boat would have no chance at all.
Leaving all that aside, things really weren't that bad until the silly climate lectures started, and it really fell apart with the methane revelation. Talk about bad science! And if the earth did get enveloped in the biggest methane bubble that it could produce, would it really take 8,000 years to get over it? I kinda doubt it.
Much has been said about the nonsense of Mrs. Safranek getting cold feet at the last minute and bailing out of the whole thing. It almost looks to me as if they had already partly shot the film and she needed to be hastily written out of it, for reasons we wil never be party to. That would be consistent with her sudden disappearance. Then again, it would make sense to shoot the scenes of the actual shrinking at the very last, because they involve shaving everybody's hair and eyebrows off. It wouldn't do to have to wait for Matt's hair to grow back.
Anyway, the science of the shrinking process isn't much better than the rest. But, so what? Is it a good watch? Yes, up until the last half hour, when the wheels fell off. So, I suppose it could be recommended, with the warning to disregard the silly ending, but you'd realize that, anyway, albeit too late. But I wouldn't spend a lot of money on it. As for the satire, I didn't see any. At least, not the American kind, where they rub your face in it to make sure you got it. But I didn't see the other kind of satire, either. Not much of any kind of humor.
Finally, I would say that this isn't really Matt Damon's kind of film, so I don't know why he did it. Needed the money, perhaps. Not that he didn't do alright with what there was to work with. I'll give it a 6.
