I just watched the two hour season finale a couple of nights ago. I thought it was a pretty decent show. There's very little good sci-fi left on television since the Sci-Fi Channel became the SyFy or "Syphilis" Channel as I like to call it. (It's like syphilis for your mind!) These days, I'll take it where I can get it; I often end up hopping across the pond to BBC America and watching Doctor Who.
A lot of people keep noting the positive depiction of Catholics in the show, which I appreciated, but it really isn't a major enough factor in the show just to like it for that reason alone.
Interesting side note, last October at the New York Comic Con, I saw Noah Wyle and Moon Bloodgood apparently promoting the show. I couldn't get their autographs as the line was closed. I arrived late because Katee Sackhoff (of Battlestar Galactica) was late to her autograph signing, and I was waiting in line for that. I was kind of disappointed because I was looking forward to looking Noah Wyle in the face and telling him how much I thought TNT's Librarian TV movies sucked (pardon my French of course).
Has anyone out there seen them? They truly are aweful.
