When I watch a sequel to a movie I enjoyed, I often imagine what the moviemakers said to themselves in deciding to go ahead; either:
I'd really like a sequel to at least pretend that it's not all about cash-sucking. And, unfortunately, this one doesn't try that hard. Although there are some cute moments, and John Leguizamo is really good as the voice of Sid, the sloth. But it's mainly bland and prefabricated.
