Review - Drinking Buddies

I've watched this movie in Christmas Holiday, well at first I thought it was a fun movie since the title is Drinking Buddies. The cast of the movie are Olivia Wilde as Kate, Jake Johnson - the new Girl actor - as Luke and Anna Kendrick as Jill.
Kate is Luke's work friend in a beer factory, they share a lot of things together. As a co-worker I really get the point of this kind of relationship. They share lunch together, share the laugh, and after office hours drinks.
Kate have a boyfriend for 8 months name Chris, and Luke has a girl friend name Jill. They have their own world during the day, and another world with their own partners. Kate's boyfriend is a music producer whose hobby is reading books, and Luke's girlfriend is a teacher. You see they have a different level in hobby, mindset and it feels like they live in a two world. This was shown in the scene of their holiday in the beach, where Kate spend time with Luke playing card, and Chris walking the track with Jill.
I won't say how this movie ends, I will let you guess what will happen between the four of them. If people says that opposite attracts, well not everything in the opposite attracts each other I suppose. We all need something in common with our partner, a feeling of mutual needs sometimes crawling from inside us and ask to be fulfilled.
Some of the scene feels quite boring for me, less friction between Kate and Luke kind of turn off my mood in the middle of the movie, but I kept wondering what will happen next.
Well, why don't you try to watch the movie and tell me what's your opinion. Anyway, I give this movie 3/5 stars!
