I haven't watched this since episode 2, but I heard Christina Hendricks was in the latest one so I caught it on the On Demand channel, and it was pretty good, story-wise. Although it was the second show I watched on demand that day where the killer turned out to be the old friend of one of the regulars -- I really should've seen that coming, since it's always the old friend, isn't it?
Although I'm still not fond of the show's cast overall. Delany and Ryan are fine (and I love seeing Ryan get all commanding and strict and pull out the old "Resistance is futile" voice), but I don't like any of the other actors.
And Christina Hendricks is rather impressive. I was thinking that if they ever make a Gilligan's Island movie, she'd be ideal for Ginger.
EDIT: Okay, now I've caught the remaining two episodes via On Demand, and they were pretty good. I've seriously reassessed this show. At first I thought Megan was just another House knockoff, another entry in the cliched category of misanthropic genius crimesolvers. But instead that seems to have just been her starting point, and the show is about her journey to become more compassionate and engaged with people, to redeem her past mistakes, and so on. I love stories about redemption and self-improvement. So now I'm sold. I'm starting to warm to the cast a bit more as well, or at least getting used to them.
