Last week I mentioned how, with most networks taking a new year’s timeout, this is a good time to catch up with old series. This week, Ovation (good luck finding it on your cable menu) is airing one of the best short-lived series in recent memory, Joss Whedon’s space Western “Firefly.”

Three episodes will air tonight through Friday, starting at 5 p.m., with the night’s cycle repeated at 8 p.m. And if you missed Monday’s two episodes, a full-series marathon will air Saturday starting at 9 a.m. and lasting until midnight.
