I never saw the first one in the theater as I didn't expect much from it (giant robots fighting giant monsters... whatever...). After watching it at home, I kicked myself for not seeing it on the big screen. It was probably the funnest movies of 2013. I'll definitely be in the theater for this one.
It was a lot of fun seeing it in the theater.

I suppose part of my concern is that Del Toro isn't directing this one, and that can make a significant difference. That's not to suggest that Steven DeKnight won't do a good job, by any means, but I like Del Toro's work and he's someone I've come to respect a lot in the genre. I don't really have much prior experience with DeKnight's work on television, so we'll see what happens.
