I came into this show expecting nothing, especially after FlashForward was't able to keep me hooked after 3 episodes.
I can safely say that I will watch this series to the very end. I loved it. Elizabeth Mitchell is awesome as always (actually didn't know she was the lead in this show), characters are interesting, dialogue is well done etc. Only thing I don't like is the son. He seems like a generic teenager I've seen too much already.
Basically V is the EXACT OPPOSITE of FlashForward to me. Now I'm going to send hate mail to ABC for the mega break that is coming up that will pretty much kill this show. Seriously, 4 episodes and then a 3 to 4 month break? Seriously, ABC? SERIOUSLY?!
Oh, and for people who care about demos/viewers: V got a 5.0 demo/13.9 million viewers, making it the highest rated television premiere on any channel since Lost in 2004. Let's hope those people will return after the break.
