Very Good
I had this stacked on our DVD collection and pulled it our on a whim. Excellent film. At first we were making fun of the staginess of the scenes then at some point the whole thing starts to make sense. A lot better than the reviews. It will stick with you.

Once Upon A Time In America
I enjoyed this film when I viewed it on a non cable channel and enjoyed it. But when I bought it I was shocked at how disgusting and perverted it is. There are all kinds of sex acts going on between minors, and teenage prostitutes, it is just terribly disgusting. There are numerous scenes of full frontal nudity many scenes of rape with nudity and unusual positions (if you know what I mean) during the scenes, it is disgusting. I am a huge fan of Robert De Niro I own The Godfather Part II, Raging Bull, The King of Comedy, The Deer Hunter, GoodFellas, Casino, Analyze This, Analyze hat and Midnight Run. But this crossed the line between tasteful and disgusting, see it on television but do not dignify this perverse behavior. The only interesting part is the acting of Robert De Niro, Burt Young, and Joe Pesci.

Stunning portrayal of wasted human lives
Director Sergio Leone has produced an ambitious, complex, and moving portrayal of Jewish gangsters in the early 20th century. When the aged former mobster Noodles Aaronson (Robert DeNiro) is summoned back to New York, memories of his childhood gang and subsequent rise in organized crime resurface, as does the mystery of what happened to the money the gang had been pooling since their first days together. The answer to that question--and the payoff to this fine film--renders one of the most moving portraits of betrayal and wasted lives that I have ever seen committed to film. James Woods delivers an explosive performance, as always.

Too many flashbacks
The movie action was great(I've watched it several times) but I can never figure out the ending. I'll watch it again in a month or two.

Not a "Mafia" movie
There have already been nearly 300 reviews of this film posted and I will not add to the large amount of commentary except to say that it is a grievous mistake to call this a "Mafia" movie. The gangsters are Jewish and there was a very real subculture of gangster activity among the immigrant Jews in New York. They may have crossed paths with Italian gangsters from time to time, but retained their own structure and organization. Secondly, this is surely not a great DeNiro performance. It takes nothing away from DeNiro's greatness to say that he virtually sleepwalks through this movie. That's fine, really, not everything this master does is great, as people who have seen some of his real clinkers know.
