Marty usually has very interesting things to say, but this commentary especially is very, I hate to use the word, honest.
I agree, most modern films' commentary sucks, but Scorsese and a few others who know what they're talking about are well worth your time to listen to. If you ever have a LOT of time to kill, there's a really good comment track on OUaTiA. Robert Skelton(I know thats not the right last name. It starts w/ S though)does a really good job
