I am also wary of the new Punisher film, although I do not share your sentiments about the original. Having received the DVD as a gift and watching too many times, often inebriated, I have come to realize the true genius of the first film.
Dolph Lundgren was a genius! Chemical engineering degree, world karate champion. I suggest you watch the original film, you'll see it in a different light after the fifth or so viewing. I know I did.
