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.)
Critical Dissonance: The movie was not well-received by critics, sitting at 29% on Rotten Tomatoes. However, it has an audience rating of 63%.
Cult Classic: The movie didn't exactly crush it at the box office and nets some derision from comic-book purists, but is well-liked among action buffs for being a throwback to gritty, oldschool shoot-em-up flicks at a time when The Matrixcopycats were still all the rage.
Follow the Leader: The skull logo; this version of The Punisher skull had been used in other Punisher-based merchandise past the release of the film like shirts, car decals, gun customization, and the skull used in the 2017 Punisher TV show is based heavily one the one in the 2004 film.
"My father and mother send their regards" becomes funnier after the Red Wedding in Game of Thrones.
In the 2005 video game, Matt Murdock became Frank Castle's lawyer. It happens again a decade later in Daredevil season 2.
Jerkass Woobie: Frank. He's cold, unpleasant, and his quest for vengeance leads him to do some really horrific things, even if the victims do have it coming. But considering how he lost everyone he ever loved, it's hard to not feel sorry for him.
Magnificent Bastard: Frank. Prior to going all out on the Saints, he works in the shadows to sabotage their operations discretely. He also manipulates events surrounding Howard Saint's wife and best friend to make it look as though they're having an affair with each other, driving Howard to murder them both. Once the mobster is thoroughly defeated, Frank reveals the scheme to him as one final humiliation before he sends his enemy to a fiery grave.
Howard's "screaming" when his legs catch fire in Frank's trap — it sounds like he's merely slipping on a banana peel instead of dying in agony.
Livia's Stock Scream when Howard throws her off a bridge and onto a train track — she does another one as a train runs her over.
When Frank is fighting one of Howard's mooks during his shootout at Howard's club, he shoots him in the foot, making him give a comical groan. Then Frank pins the mook's hand behind his back and stabs it, making the mook give out a yell of pain that suspiciously sounds like he's doing opera. And then Frank stabs him under his jaw, with the result looking darkly silly.
