Remember Eureka? Syfy's other goofy show about quirky people who solve wacky problems, with a large dose of good humor? Eureka used to be known for its endless genre pastiches — and now, Warehouse 13 is doing them too. Except with a huge dose of metafiction, and a kernel of emotional pain. It works way better this way.
So yeah, this was an insanely goofy episode of Warehouse 13, even by this show's standards. And like Burke says over on O-Deck, there is a lot of hamming it up here. In the "A" story, Myka and Pete get sucked into a hard-boiled detective novel, with a lot of the trappings of a film-noir (including being in black and white), and at first it looks like just another one of those "trapped in a story" things, like Star Trek: TNG's "The Royale." Meanwhile, the "B" story is pretty thin — someone is stealing classic cars, and Artie is being reckless because he can't face the guilt over Leena's death — but it includes the awesome 1970s Bullitt moment above.
