So, speaking as a long-time and obsessed fan of the comics, The Punisher was, in a word, awesome. It had good acting, but I didn't like Dave and Mr. Bumpo. I thought that the comedy brought on by their roles didn't fit in with the more serious tone of the movie.
I liked some of the more creative killings (ballistic knife, arrow thru the neck, etc.) and, as a gore freak, I liked the copious amounts of blood that comes with them.
By the way, I think that they changed too much from the comics. First off, Frank was a Marine, not an FBI agent. Secondly, his family was killed because they witnessed a mob hit, not because Frank pissed off Howard Saint (who wasn't even in the comics). Thirdly, the comic takes place in New York City, not freakin' Tampa.
I have nothing to say about the special features and whatever because it has not been released at the time of this writing.
