And as a side note: How is it that Kristen Bell (Veronica) wound up on Heroes this season, but Jason Dohring (Logan) got screwed with a role on CBS' craptacular (but still more watched than Reaper) Moonlight? Now Ghost Whisperer is suddenly high Friday-night art ... sorry, Logan.
Back to Chuck and Reaper: The only similarities are that the shows' leads work in big-box stores and happen to be as good-lookin' as TV stars. That's it. Chuck is an action series with hints of humor. Reaper is a comedy with several toes in sci-fi. When the action slows down on Chuck, the funny ain't there to carry it. Reaper rarely falls flat, no matter what mode it's in. If it were on a real network—say, as a lead-in to Heroes—Reaper would be a Fall Smash. As it is, it's just barely beating out Life is Wild (debuted to exactly 35 viewers last night) and your webcam.
So watch Chuck tonight (and then the multiple reruns on NBC properties Bravo, USA, Sci-Fi, CNBC, MSNBC, Telemundo, etc.), and watch Reaper REALLY HARD tomorrow night. Who knows, could help ...
