For many shows, airing at least one holiday-themed episode is sort of a tradition. Christmas seems to be the most popular subject, but appearances by Hanukkah, New Years’ Eve/Day, Thanksgiving, and others are certainly not unheard of. Having lasted an impressive ten seasons, Smallville had plenty of time to air plenty of episodes about plenty of holidays, and in Season Five, they decided to go the spooky route with a tangentially Halloween-themed episode, complete with costume parties and hot lady vampires. Boy, was that ever dumb.
The ONLY bright spot here is that this was made before Twilight, so they couldn’t rip it off or make “fun” references. And that is the only Twilight reference I will make in this review. I knew you’d be expecting it, so I got it out of the way early so that, like the later Hitchcock cameos, it won’t distract you from enjoying the rest of the show. You’re welcome.
