Its a pretty entertaining movie, but its pure entertainment, dont expect plot heavy scenes or complex dialogues or stuff like that. This is no Godfather or Heat, just an entertaining gangstar movie.
I also dislike how they have Ryan Gosling in this movie. Hes a totally mediocore and overrated actor, not suited for this type of movies, can produce 2 - 3 different emotions at best, even Keanu Reeves has more expressions in his face.
