It's a brilliant movie. The concept is the kind of inspiring idea that makes you feel like you could write tens and thousands of new stories within the movie's fascinating universe. Not to worry through, this isn't one of those Hollywood block-busters where countless sequels will instantly emerge at the slightest success of the original idea. This simply isn't the kind of movie to have sequels. It's one of those interesting artsy movies where the whole story is really a metaphor. I'll say it's a metaphor for the society. You'll have to figure out the rest.
Just on a sidenote - the basic idea itself might made a cool classic sci-fi film too. People living in a house where floors dictate your social status.
It's one of those films that requires a lot of thinking and attention and interpreting on viewers part. Not an easy ride, but a fun one none the less. At least - in my opinion. Gruesome and graphic at times, but not really heavy. Just deep and thoughtful. There is a lot of interesting really innovative camera angles and work and that says a lot at a time when it really seems that it has all been over and done.
I personally also really enjoyed the soundtrack. Especially the Portishead's cover of ABBA's "SOS". Brilliant. Same can be said for Tom Hiddleston's acting. As always he brings a lot to the character and is generally great. I like the esthetic of the film too, although at times it oddly reminded me of those Estonian movies they make of Soviet times now. Well - the original novel was written in the 1970s. A novel which I would love to read if it was available in any of our libraries or even bookstores. I take ages deciding whether something is really worth ordering online...I'm sure it's worth it, but what if it comes on sale here with the DVD release?
