I saw this quite some time ago (Sat a few rows in front of the beautiful Anna Kendrick)... it was an amazing movie.
At first I didnt like the first person camera work, but it goes in and out of it in a way that isnt a distraction.
In reviews I have read the ending is a bit "Hollywood"... the cut I saw was not "Hollywood" by any stretch and was fucking amazing.
If anyone else can spoiler tag the ending for me in here, I'd appreciate it, then I can see if they changed it.
It was just a great movie with 2 characters that are good friends and have a great relationship and joke with each other, and the story follows them uncovering a drug cartel in southern california.
Really solid movie that everyone should go check out.
