Just finished watching it. first hour was awsome. Second hour was kind of slow but I liked the outcome. Because it is really what I believe happened in real life, or something similar. (Sorry I'm being cryptic - I'm trying not to post spoilers. lol)
I would say that over all it wasn't unsatisfying. I hate that it's over, but I am glad it actually concluded, instead of cutting off mid-story like just about every good show Fox runs.
man I wish Firefly had been a SciFi program. *sigh*
