Movie Review: Divergent

First of all i have to admit, if you haven't read the book. this is an amazing movie! But i did read the book and that's why i think personally that the movie sucked.
The plot is so much different than the book, I expected a few changes, but not so many! I think that the explanation of the factions with Shai as narrative wasn't that good, i think they could have done it another way. The actors were amazing, Theo and Shai (OTP) and the movie Christina isn't the one i pictured.
But there's always something bad... The confusion between will and peter. Yes thats right, those two really looked like each other and i always had to ask myself who is that? Will or Peter?

I really expect Insurgent to be better.
