The Number 23 isn’t unwatchable by any means, but its particular brand of awfulness deserves a little explanation. Directed by affable hack Joel Schumacher, the movie is part of what I’d call the post-Memento film, featuring unreliable narrators, plots that twist upon each other, suitably grimy production design that screams “I must be insane because I wrote all over the walls,” and the pleasures of the readerly text. Its saving grace is that it doesn’t constantly tease you—“constantly” being the operative term here—with “Was that real, or did he just dream that?” At least the whole thing is wrapped up neatly with a bow at the end, which is the least one can demand after having to sit through this.
Tonally, the film is all wrong, too. The pulpy novel that propels Walter Sparrow, Pet Detective, into his Downward Spiral Into Madness is meant to be badly-written hardboiled dialogue—actually, most of it is badly written period—but Schumacher seems to take it fairly seriously. Instead we get Jim Carrey doing his best brooding Colin Farrell impersonation; it’s a problem when the audience isn’t sure whether to interpret this as camp. (To his credit, the writer makes Carrey’s character a dog catcher; this can only be deliberate, considering one of Carrey’s most famous roles, but some sequences—particularly when Sparrow is pursued by the Hound of Heaven—are inadvertently funny.)
In short, the best thing about the movie is Virginia Madsen’s cheekbones, and they’re not reason enough to watch it.
(And to Mr. Schumacher: when your oeuvre contains the infamous “Fi’ cent” scene from Falling Down, it’s not very cool to start with an elaborate, unfunny joke that ends with the punchline “In China, people eat dogs.”)
