Mediocrity topped curiosity at the box-office this weekend, with two tepidly reviewed holdovers — Blades of Glory and Disney's Meet the Robinsons — landing in the No. 1 and 2 spots with $23 million and $17 million in ticket sales, respectively. Both movies beat out Grindhouse, the groundbreaking double feature directed by Robert Rodriguez and Quentin Tarantino, which earned just $11 million.
