A very boring How To Train Your Dragon knockoff

How in the holy mother of hell would you waste a great cast of talent like Freddie Highmore, Antonio Banderas, Alfred Molina, Mark Strong, Rupert Everett, Saoirse Ronan, and Julie Walters for such a terrible boring movie like this?

Predictable story that wastes an interesting idea (and feels very derivative of How To Train Your Dragon) , puts too much emphasis on exposition, has cliched and bland characters, terrible script, and dull pacing. I can't see anyone else liking this. 3.5/10
