The idea of spoofing 70s sci-fi TV shows is great, even if it's been done before. (And better, as in "Galaxy Quest.") This has all the right trappings in terms of sets, costumes and soundtrack track choices, as well as a game-enough cast. But where is the script? There are a few half-baked comic ideas here, but few if any of them are developed beyond the level of the verrrrrry mildly amusing, at best. There's less than a SNL skit's worth of actual laughs here. Worse, the characters are mostly irritating, with ideas that are potentially funny (Wilson's Captain being a closet case) and those that really aren't (two sets of bad, oblivious parents) both simply repeating themselves without building toward any big payoff. In fact, what they build toward is a weirdly serious scene at a Christmas party where everyone reveals how much they hate each other, something that might actually be cathartic in a movie that WASN'T aiming to be a comedy. I just don't know what the filmmakers were thinking. It's very strange to go to all this trouble and expense to mount a sci-fi fantasy satire, and seemingly forget to include much in the way of actual humor. No, the humor wasn't too "subtle" for me--deadpan is one thing, but this was just flat and lacking wit. A pity.
