We loved it, and can't wait to see it again, because it was so captivating.
I also liked...
Spoiler:
...the fact that they touched on a very real issue about the increasing sedentary lifestyles that people are succumbing to these days. I especially liked the display of showing how people get so caught up in the screen in front of them, that they don't even notice people actually next to them, or that they can socialize outside the screen. Again, that's a very real aspect of today's society, because a lot of people are spending more hours online than they do offline, thus ignoring the real world around them.
Visually, it's an absolute masterpiece, and I almost wondered what sets they used for filming.
I'm very happy we finally have a film that not only provides breath-taking entertainment, but provokes thought as well.
