With a budget of $20mil it should have broken even the first week considering the fact that 3d animated movies does well and no stellar new titles the weekend.

The rule of thumb in the movie is make at least twice the budget to break even. There are other heavy hits coming this may which is going to be difficult to rake the desired revenue. Hope, Rainmaker studios don't lay off staff who have put in their best.
