The vast majority of the jokes fall entirely flat and I think an insanely fast-paced movie with an hour-and-half runtime should have been way more entertaining. The major issue I have with this, though, is that it keeps shifting from one interesting storyline to another, and trying to convince us every time it that this would be the basis of the plot, before almost abandoning them and settling on a rather far less interesting and original plotline to serve its message, which is very problematic.
That said, I did enjoy this. It's so silly, for better or worse, and has a tinge of freshness, extremely eccentric and quirky characters (I think these parents are the creepiest I've seen in any movie) and breezy animation style similar to what Kris Pearn has done in Cloudy with a Chance of Meatballs 2. But, to be honest, the intrusive meta-narrator cat is the true highlight of the movie.
(6/10)
