"Heights" was a victim of people not wanting to see it in its first weekend. I don't understand why y'all are having such a hard time accepting that. Next you'll be asking for a recount of the receipts and testing if there's too much bamboo in the fiber content.
Maybe word of mouth will help the movie, or maybe it's just too niche and too arty to break into mainstream success. We'll see if their box office picks up or flatlines this next weekend.
