Are you seriously saying all of this merely because Thomas Jane left the project?
Think about this, now. The film would be a sloppy mess if he became the Punisher the very next day and not went after his family's killers. What kind of a plot would that be if he just turned vigilante over night, then decided to hunt after his family's killers another day. Believe it or not, The Punisher came BEFORE alot of those films. The films are essentially copying off of the Punisher, not the other way around. Besides,
The Punisher was an origin story. It was a revenge story, then at the end of the film, he finally became The Punisher.
I agree. It was basically Punisher Year One.
