They spent $18 million on this...
Which seems like a lot, but really the average 3D animated film has budgets upwards of $100 million. Did they think they were going to make something half respectable on that low budget? If they wanted to save money, they should have just made it 2D, maybe it wouldn't look like a piece of 💩.
