I made the mistake of watching the trailer before I saw the film, because the film ended up being very different. The trailer gave me a Walter Mitty (which I love) vibe, but I barely felt it in the movie.
Normally that would be fine, since I mainly just wanted to see life in a small world. I didn't really get to see much of that, either. Honestly, the first and second half felt like two different movies, at least to me anyway. The ending was also very abrupt, and I couldn't help but feel glum (due to the whole
end of the world thing, I suppose) afterwards.
I just felt like it could've been so much more. It could've shown so many things, it could've been so incredibly fascinating. Instead, after the amazement wore off I mainly just felt like I was watching small people
live exactly like big people. There were a few moments and cues that reminded me that they were small, but it just felt so unfulfilling, with such incredibly wasted potential.
Apparently (judging by some of the comments) this means that I don't "get it" and either need to watch it a million times or put on my thinking cap. I really don't want to do that, though. I'll leave that to someone else instead.
It was good, but I wouldn't see it again.
