I'm not exactly a kungfu movie fan (hell I'm not even sure I've seen just one Bruce Lee movie /before/ KB), but enjoyed KB a great deal nonetheless.
Kurt Russell is just great and probably not nearly as appreciated as he should be. I loved him in Big Trouble in Little China and can't think of any actor who've been able to do a Snake Plissken character AND then turn it upside down into a comedic role with the degree of confidence and the effectiveness Kurt Russell achieved.
PS: I re-watched Escape from NY a couple weeks ago after a long, long time. That movie really deserves a special place among the classics.
