I guess it depends on how you take it. To be honest I came out of the theater feeling dissapointed in the last part of the film but admittedly (at the time) snickering and patting myself on the back because I was one of the "ones who got it" (pretty sad huh?). Its hard to say whether or not it was worth it to sacrafice 2/3 of a really good film with a shitty ending just to try and prove a point, but for me the first part of the film (which I really enjoyed) and the fact that they were willing to take a chance like that made it worth it to me. But thats just me. :)

Also did Donald Kaufman really write the last part of the film? I know thats what people are saying and I know he's credited but I was just wondering if you knew for sure.
