I am sorry to say but next time I have a conversation with a guy against "piracy" I can pronounce two words and win the argument: Shutter Island. A waste of time and money, plain and simple. Even worse than "Public Enemy".
Having in mind Pulp Fiction didn't impress me either I should say that maybe it is that Scorsese fails to impress me in general. But after Pulp Fiction I wasn't like "damn, can I return back to three hours ago?".
What I didn't like? That in the last 10 minutes everything that I have seen during the last 2+ hours got so not important because it was a lie. It wasn't true anymore, just the guy's illusions. That Scorsese thinks that all you need to add more mystery in your movie is loud music. That the twist was so damn predictable after a while.
I am not going to write any more things, after all I watch every movie I want to watch even if everyone is telling me not to do so. And I think it's right that you do so as well. Just don't say you were not warned.
