I only saw one commercial for it, but the series teaser looked interesting enough. Sleeper Cell is a Showtime original (and they're well on their way to becoming my favorite cable channel, especially if they pick up Arrested Development). I recorded a couple of episodes on my PVR, but found them infinitely easier to watch while I was working out in the other room. If you haven't caught Sleeper Cell yet, I'd strongly recommend doing so. Sadly, Sleeper Cell was only a miniseries – although I would implore Showtime to push this show into a second season. Showtime has even posted behind-the-scenes interviews with the principal actors, although I'm still recovering from last night's season finale. It's not too late to get into Sleeper Cell, by the way; there are only ten one-hour episodes to watch. This isn't a Sleeper – it's a Keeper. NPR agrees.
