The summer ends with only two August openers over $14 million (smash "Straight Outta Compton" and the disastrous "Fantastic Four"). At least the new releases over the past two weeks haven't been that expensive (marketing does add up). And faith-based new entry "War Room" not only far exceeded expectations, but will move on and prosper and wind up profitable for all involved. The next two weekends normally don't hold hope, but there are boffo openings ahead for Venice titles "Everest" and "Black Mass," at least.
