The real pitfall here is how bad and unenthusiastic the voice acting is. I was interested that Patton Oswalt and Ron Perlman were in the movie -- Oswalt as the fish man Aesop and Perlman as the villain -- but was shocked by their performances. Perlman in particular sounds monotone, as though he’s reading a phonebook. He has an extensive resume in videogames and animation, so I can only assume his lackluster performance here is because of a lack of direction or knowing that the material wasn’t worth the effort.
