As someone who is borderline obsessed with the Gotti/Gravano story, I have read nearly every book, and seen nearly every movie and documentary on the subject. That being said, I feel this film is vastly superior to HBO's "Gotti", not only in production value but in taking less liberties with the story. The movie pretty much follows Sammy the Bull's book "Underboss" to a T. I feel this is pretty accurate, except it portrays Sammy as too much of a saint. "Gotti" does the same for John Gotti, of course, and it also shows Sammy to be kissing John's ass a little too much. The production, costumes, acting, music, and attention to detail are all far superior in this film.
As far as the acting goes, Nick Turturro does a good job as Sammy, although he's a little too stocky and way too dark-skinned. Sizemore is excellent as Gotti, his performance probably at least equaling Armand Assante's portrayal in "Gotti". I much prefer Abe Vigoda here as Paul Castellano to the actor who played him in the other film, and one of my favorite actresses, Debi Mazar does fine as Sammy's wife Debra. The rest of the cast are mostly Sopranos actors, many of whom played different parts in "Gotti". Michael Imperioli, who wasn't in the other film, does a fine job here as Sammy's longtime friend Louie Milito.
All in all, this is certainly no "Goodfellas" but in my opinion is still very good and much better (and more accurate) than "Gotti".
