Space Shuttle DiscoveryWhat we're watching: We hate picking the same show every Monday, but let's get real: when you have back-to-back eps of "24" on Fox, how can you pass that up? The first episode must not be that violent for two reasons. First off, it's on at 8 p.m. and some of the kids haven't hit the sack yet. Second, the episode takes place between 5 p.m. and 6 p.m., so there must be some time off for dinner, right? Seriously, when do these characters ever eat or hit the bathroom?

If you haven't been sucked in to "24" on Monday nights, we'll offer up her Halle-ness at 9 p.m. in "Catwoman" on HBO-HD in 1080i, more for the visual effects than the plot. Regardless of what you watch in the early evening, we have to recommend "Return to Flight HD: The Inside Story" at either 8 p.m. or 11 p.m. on Discovery-HD. Walter Cronkite hosts this 1080i look at the Space Shuttle Discovery and STS-114.
