Beside the terrible acting, nothing really makes sense in this movie.
Everyone is frantic, until the next situation. Then everyone is frantic again! Why? The father and son look like they're both Grandpa. The Mom is way too old to have a 10 year old. There is a mixed race girl considerably older than the other 2 siblings in the family, that has no explanation. All of these things paired with English voice-overs that don't match the character at all, make this movie a disaster. Worst movie I've seen, second only to The Green Knight, which wasn't a parody, but should have been.
