I know Troll Hunter's a found footage-style film, but don't hold that against it—it's not a Blair Witch/Cloverfield ripoff, where you never know exactly what's going on. It's got a distinctly Hellboy-esque sensibility, and there's some serious nerdy world-building taking place throughout the movie. The thing that saves the film from being a bore is the titular troll hunter; he's a marvelous concoction, a wearied working man who's getting really tired of his shitty job. It's just great fun all around.
Troll Hunter plays again at the Neptune on May 24th at 9:30 pm. You should go.
