Just came back from the theater.
Quick thoughts about it, without any spoiler:
It's a very good move IMO.
Let's say a mix between Cronenberg's The Fly and a good Shyamalan movie (yes there are some!).
It's not a movie that scare you though. Aspects of it can be disgusting to some people, but to me I would say that the movie is beautiful.
Good direction, good acting.
The story is not as original as I heard, but it's an intersting take.
I only wished the movie was 2:35:1, it would have been even more visualy stuning.
Best use of CGI in a movie I've seen in a long time. No "money shots" to makes you "woaw". Just CGI used to tell the story. Quite clever.
I don't think it's a movie that would please everyone, but I think it worths a try.
