Merlin is back, and if you haven't caught up with the first season, DO. It's kind of like Smallville (in how it fits with the main mythology arc) only with a healthy disregard for actual Arthurian anything, and also a healthy dose of gay. The plots are fairly predictable and the writing is often unintentionally hilarious but the cast is gorgeous and reasonably talented, and it has Giles. I mean, what more do you want, really?
