Anybody feel like this movie is missing alot to it?

I've noticed when I watched this a few days ago that something felt left out.You know like it was badly edited and alot of the footage was left on the cutting room floor.Or maybe it was too violent for an "R" rating.I have heard rumours about a longer cut of the film,but haven't found the proof yet.Does anybody know if there is cut footage and what exactly was it?This reminds me of another film called Once Upon A Time In America with Robert De Niro and James Woods.That was edited really badly for the USA audience,but not overseas.Eventually that cut re-surfaced here and it made a difference in the movie.Now I know these are two different types of films and probably shouldn't even be mentioned in the same topic,but I was just trying to make an example.
