BOM - While it did finish in first place, New Year's Eve dropped the ball this weekend with a disappointing $13.7 million opening. Things were comparatively better for The Sitter, though Jonah Hill didn't impress in his solo debut. Adding these two movies to an already weak field turned out to be box office poison—the Top 12 wound up with an estimated $69.7 million, which is the second-worst gross of the year so far. There is also a very good chance that once all movies report tomorrow, overall box office will wind up at its lowest point since 2008.
