Just finished, cracking movie,.........................erh I'm not sure if its suitable for a 16 year old,.................but highly recommended, Di caprio is not my favorite actor by a long shot, but he was spectacular in this. If you like Goodfellas you will like this.
By the way I watched Last Vegas last night, and for the love of god, please don't waste your precious time on this its horrible and shite, De Niro is on a mission to ruin his whole career with terrible movies, don't indulge him .
