Meh

Rating: 5/10 (28 February 2015)

The movie seems to have had nobody in charge, just a committee with a checklist of popular trends and plot clichés.
Cloudy with a Chance of Meatballs / Big Bang Theory- lets have science nerds! check!
Boy and dragon? Let's have boy and robot! - check!
Pathos a la Bambi - check.
The script was written in minutes, you can see the scotch tape holding the plot pieces in place. There is no attempt to make anything believable, we just have a lab full of magicians doing sciencey stuff and talking gibberish. The characters that are nominally Japanese have been drawn without any effort to make them look Asian, either from timidity or carelessness.
Spoiler alert: 500 degrees Kelvin is 440F, not as hot as your oven when you heat up frozen pizza.
