Yeah, I've been watching it. It's one of the few shows that I bother watching on TV when they air (instead of watching it later on DVD, etc.).
I started watching it 'cause I thought it was (and still is) hilarious and a clear copy of X-files with just a role reversal (Mulder = Olivia Dunham, Scully = Peter Bishop), but it has been getting better now that they've established a (somewhat interesting) longer story arc.
But overall, I still think it's so cliche and predictable that I'm surprised they even put it up considering how much X-Files exploited the formula and how much modern Sci-Fi series have advanced in terms of quality story telling (Battlestar Galactica). Then again, it's Fox and I haven't even seen a single episode of Lost...
