Steve Martin never appealed to me, going all the way back to his SNL days. His style and brand of comedy leave me completely uninterested.
After years of resistance, I finally watched two movies I thought he was fine in -- Leap of Faith, which I rather liked, and The Big Year, which doesn't do anything for me but I can get through it. I believe I found him fine in Dirty Rotten Scoundrels but I haven't seen that in years.
I, too, only ever saw the original Pink Panther film. That's not 100% true, as I know I've stumbled across one or two of the sequels on TV and maybe even enjoyed a scene or two. But I never sought them out and really watched them. I wouldn't go near the "remakes" with somebody else's ten-foot pole.
