I've seen some clips from this and it looks REALLY good.
Count me in for two folks for mid-day Saturday. I don't know if I can wait that long, I would have gone opening night last weekend had I been in town! So I might go an evening this week but count me in for Saturday no matter what.
I don't think it's playing at the Chinook IMAX. Eau Claire's screen is bigger by a few feet so better to go to Eau Claire anyways...
