Divergent

Not really.  Normally, I only go up to red if a main character dies, but the deaths that do occur are so traumatic here, that I'm bumping it up.  Tris and Four survive, but several other sympathetic characters die.  And the things that Tris is forced to do in this movie are going to leave serious psychological scars.

BONUS TRILOGY SPOILER:
In the final book (so presumably also in the final movie) one of the protagonists sacrifices themselves to save everyone else who hasn't died yet.

BONUS ANNOYING NOT OK:
The studio has announced that they're splitting the last book into two movies.  Not ok.  Maybe...MAYBE some books can justify that.  If anything, this series would work fine with the last two books being combined into ONE movie.

BONUS OK:
Theo James.  Theo James is ok all day long.

BONUS WEIRD NOT OK:
It's not the movie's fault, but the actor who plays Tris' brother plays her love interest in The Fault In Our Stars, also coming out this summer.  If you are a YA fan/have a YA fan who drags you to movies, you're going to see that movie this summer and just...weird.
