I'm definitely going to see it a few more times. I want a sequel, dammit! I usually don't care much about box office, but I like it when films I support, do well. If I want a sequel, I'll usually post about it on my facebook, tell friends how good it is, go see it myself several times.
Maybe they waited too long? ST 09 was four years ago. Audiences are very fickle these days. The general audience has probably already forgotten Trek 09 and moved on to the next thing. The last one generated positive buzz, or so you'd think. I hope I'm wrong, and people just couldn't make it to the cinema Thursday night because of work or school.
