It's not like it was that great of a movie to begin with. I think people get upset when people mess with the classics. Like this "Truth About Charlie"/"Charade" remake. What's up with that? Mark E Mark taking on Cary Grant? That's got to be a joke!
Anyway, the original film is somewhat obscure these days, and I think the story could easily be modernized to today. I mean, the opening episode of the new Twighlight Zone series did just that, though it played more like a drama you'd see on Nickelodeon.
