Saw this yesterday with my fiancee, and we both loved it. I never loved TOS - I was 10 when Star Wars came out, had never seen TOS at the time, and could just never get past the cheesiness of TOS (I was a kid, what can I say?). Liked some of the movies (II, III, IV, VI), never a regular watcher of the other series, though I caught the occasional episode.
The beauty of a "reboot" is it allows them to utilize affection for the original characters and milieu, without being bound to them. I loved the pause as Kirk came onto the bridge at the end of the movie - felt just like Shatner's character, but different at the same time, and free to go off in a different direction. Would go see a sequel tomorrow, if possible.
Gads, I wish somebody had the ability to reboot Star Wars - it needs it desperately.
