If you don't care about seating it doesn't really matter when you arrive, if you're hoping on getting front row center 2-3 hours in advance is probably a good idea. The lines are long.
I'm going to be on the Sound on Sight podcast to talk about Red State, so you can listen to that on Thursday probably.
As for Detective Dee, it was a lot of fun. A bit too long and the plot gets a bit silly and convoluted near the end but the fight scene set-pieces are great. Its a Hong Kong action movie so its not really anything I hadn't seen before but I enjoyed it.
