IMDB’s description:
When Frank Castle’s family is murdered by criminals, he wages war on crime as a vigilante assassin known only as The Punisher.
Despite what the description says, this movie is not about Frank Castle and his origin story. A better description might be “Frank Castle and his one hundred and one ways to kill people while never using the same weapon twice.”
The movie opens with a mob boss being released from prison. The media is in a frenzy and ask him if he is worried about The Punisher, a vigilante who has been killing ciminals. This mob boss says no, and openly taunts The Punisher. Will he live to eat his own words? No, because he gets killed.
