I rarely go into a movie blind after the disappointment I felt from T4 & AVPR. Putting up with transit and fellow audience members is a big deal and I already decided Ironman2, Kickass, Splice, and few other films can wait for rentals.
However, I'll be using a vacation day for what I hope will be a relatively uneventful 10 or 11am opening day showing of Preds and will likely see twice to catch all the stuff I'll miss the first time.
I can barely remember my quick read of the script and have looked at early pics, but I won't watch any more trailers since the Redband/international looked good enough that I want to leave some surprises for myself. I'll also avoid any new clips, but will surely waffle should we get lucky enough to, ala AVPR, see the first 5 mins of Preds shown before release date
I'll definitely have to avoid AVPG, IMDB, and surely even IO9 should that happen.
