Not, oddly enough, my favorite. The Depictions of New York - 1910-20(??), again in the '30's, then in the 60's, all practical effects, all remarkable. The casting - Robert DeNiro, James Woods, Joe Pesci, etc - excellent, the costumes, period pieces, sets, all very worth while, the sentiment of characters with a torch carried for decades, meeting again and again to no good effect, well, sentimental to the extreme, but at almost 4 bloody hours long!!!!
One exception - the Modern Erotic Chinese art, passed over in the Chinese Theatre/Opium House scene near the beginning with Robert DeNiro -, well, I could have paused there, there was some inspiration. But that was background to a vanishing scene, like the opium dreams themselves...
Otherwise, no.
