It will cross 170 dom imo. I'm comparing the daily grosses with the first Twilight movie (2008).
OW: 69 vs 62 of FB2
By the second weekend, Twilight was at 119.7, and FB2 gained a bit, is at 117.1.
Twilight ended with 191 (it's as 192 in BOM, but that's because of a fan event held the following year).
If FB2 holds like it's doing..well, it could end up similarly. Agree?
