The ones I'd put somewhere between mediocre and bad:
New York, New York - I appreciate the effort but I only got into this one during the extended musical number. I feel obliged to give it another shot at some point but it's really long, so I'm not in a hurry.
The Color of Money - Just okay. It is what it is.
Cape Fear - Schlock. I like the original better. I will say that this one and CoM really demonstrate is integrity. It's not because either of those two particular movies have any. In fact they were made to order hits, but that's exactly my point. He traded these two movies for the opportunity to make The Last Temptation of Christ and as promised delivered the two biggest financial successes of the first 35 years of his career. He clearly could have been a much more bankable director than he actually was during that period.
Gangs of New York - Loved Daniel Day Lewis and the production design, but most of the rest was so plodding and stilted I could barely slog through it.
The Wolf of Wall Street - I thought most of this was only vaguely entertaining. It superficially resembles his gangster movies but without any ethnic or regional angles that gave those movies alot of their flavor. And I find the subject matter boringly distasteful.
I like everything else, all there are a few I don't remember too well, especially The Age of Innocence. And I still haven't seen Boxcar Bertha or Silence but those both sound appealing.
