I don't know why I never got into Martin Scorsese movies more, cause he makes all the stuff I want in a non horror movie. That stuff being gang violence and crime.
I finally watched Goodfellas awhile ago and it turned me toward his work. I can't explain how much I enjoy Casino in a short post though, so I'll leave you with a quick thought.
If you like movies about the American Mob, Vegas, and Joe Pesci being an absolute psychopath, this is the movie for you. The 3 hour run time may be a little daunting, but it's well worth watching.
