Okay. Finally watched all the rest of the episodes. This is by far the most complicated show I can remember watching--that actually makes sense and doesn't just keep making stuff up as it goes along. I mean, shows like Alias are complexity piled on top of complexity, but they get contradictory.
I liked the show. There is a hugely major loose end that isn't explained, but the final shot of the show makes clear that it was supposed to be explained in a sequel. (At least, I understood this after looking at Wikipedia. Which is a failure of the show, because the viewer is supposed to be able to recognize the significance of the final shot without looking it up.) I have very few complaints, except that it took the main character a couple episodes before his acting really got up to snuff--I wonder how much that contributed to the ratings drop.
It was a real pain to watch online. It lost the connection every couple minutes, and I had to press pause and play again to get it to restart. Wash, rinse, repeat. A real pain, but it was the only way I could see it, and I was hooked after those episodes I'd seen on TV.
