Yep. Great movie. I was wondering if the original post would get any attention.
Few movies are able to pull off that dramatic device of a surprise ending like that---where you don't know the ending until the VERY END.
BTW, I guess you'd say The Usual Suspects is a quintescential "guy flick." It's number 17 all time on IMDB.com for male voters; I don't think it's on the list for female voters.
