Better on DVD: The "Extended Cut" release; several scenes are added in that actually improve upon the film's theatrical cut and flesh out a few plot holes - most specifically, scenes with Frank's former partner, who is revealed to have sold Frank out to Howard Saint, which leads to the Castle family being massacred. (The "Extended Cut" of the film is also the one shown when the film plays on the FX network.)
Cult Classic: The movie didn't exactly crush it at the box office, but is well-liked among action buffs for being a throwback to gritty, oldschool shoot-em-up flicks at a time when The Matrix copycats were still all the rage.
Ensemble Darkhorse: Harry Heck. A Johnny Cash-esque, Affably Evil murderer who sings the tune to Frank Castle's life. Then he dies one chase later. The character made quite an impression on audiences however, and is often mentioned as one of the most memorable scenes of the movie. Keep in mind Harry Heck was nothing but a named Mook in the comics who appears and dies in one page.
