Under normal circumstances, the week of Thanksgiving would be relatively slow — but this is no ordinary holiday week. There's a whole lot to watch, including one of Marvel's best shows yet.

Though fans of Baymax are obviously geeked about Big Hero 6's small-screen premiere as an animated series, the big story this week is Hulu's Runaways. It's being touted as "The O.C. with superheroes," and though that's a bit of an oversimplification, it works. The series carves out its own corner of the MCU and has a whole lot of fun in it, introducing compelling new characters from a perspective we've never seen in this universe.

The CW is also keeping its superhero universe rolling, complete with a Turkey Day story for Arrow. On SYFY, fans get a sneak peek at the high-concept series Happy!, based on the excellent indie comic of the same name. If you're wanting to go a bit old school, a MST3K marathon will also be streaming online. Which is, let's be honest, the coolest option of all this week. Right?

Check out our full rundown below and let us know what you'll be watching:
