The cast was great. The direction was good. The story was great. The production was amazing. So, why did this movie leave me cold and why have I forgotten it after just two days?

It was ridiculously indulgent on the part of Scorcese. There were at least five or six scenes that were way too long. It was 210 minutes long and that was how long it felt. I think it would have had alot more impact had it been 150 minutes long. I kind of lost interest.
