Odd Thomas is an adaptation of a successful novel by Dean Koontz. But the actual movie has a breezy, quippy tone and a small-scale storyline that remind me of nothing so much as a low-budget 80s adventure film. It's not a great movie, or even a particularly good movie, but it's fun and cute and doesn't outstay its welcome.
Most of all, it has just enough of the secret sauce that made movies fun in the 80s to let you forgive some extreme clunkiness and way-too-precious storytelling. Odd Thomas is in select theaters today, and it's been out on VOD/iTunes for a while.
