Its out n out children film but it lacks the adventure part which is central in this genre. Cinematography & visual effects are good but its very flat & predictable one. Well you can catch some classic natural visuals of scotland in the film. Movie has fun part when the child got the egg of water horse & how he secretly keep him away with the help of his sister & plumber. Its avaerage children film with some nice visual effects & common story.
Watch once if you like this genre.
