Actually many were expecting it to open from $50M-$65M for it's international opening, so this was in some ways a breakout. I'm surprised it out opened Thor 2 internationally.
Home had barely any competition (Get Hard) compared to Trolls (Doctor Strange). However, it should do well due to lack of family breakouts, guessing $27M-$35M OW and a total from $100M-$125M. A Peanuts sized OW wouldn't surprise me.
Guessing anywhere from 55% to 65% on RT, along with a mid 20's to low 30's opening. If DS gets decent reviews it could mean some trouble for Trolls OW.
Probably Inferno. The next HUGE weekend should be November 4th, I think it's possible that both Doctor Strange and Trolls perform like Spectre and Peanuts did last year.
I kind of have to agree with Brainiac5 here, JL isn't missing $300M, at it's worst will have an big enough opening ($150M-$170M) where it will get to over $300M, even if it gets BVS critical reception or middling audience score. However, over $350M (My prediction is at $345M) would be a hard number to reach especially with SW8 and Coco, which could harm its legs.
