When the kid behind you says "Can we go now?" you know it's bad.

Rating: 4/10 (12 July 2016)

I've read a few reviews that go on and on about the quality of the animation and it is true--the animation is spectacular (it is represented by the four stars I awarded this film).
But I didn't go to the theater for the animation. I laughed every time the previews played. I laughed during every commercial. I was excited to see this film. And then I bought a ticket. It turned out that all of the funny bits were in those 15-30 second spots. I could live with that disappointment as long as there was a great story. But no. It has all the necessary elements of a story--exposition, conflict, characters, setting--everything but a solid plot. They did try. There is an accidental quest, but it goes absolutely nowhere.
For moms and dads who are thinking this would be a fun movie with the kiddos, be warned: there are some scary scenes. Even I looked away at one point (giant sewer snakes are not my thing).
See it if you want--it's your money (and your brain-cells). As for me, I went back to the theater later the same day to watch another movie just to get it out of my head.
