Good watch, could watch again, and can recommend.
It's sort of discovery of aliens in "Men in Black" meets the goofy animation of "Home".
There's not a lot to this one but some goofy fun, despite a weirdly serious plotline that gives it just enough substance to prevent me from saying it's a rather silly movie. Instead it's a decent movie with a lot of rather silly parts to it.
Probably great for younger audiences, but just nuanced enough to be acceptable for an older audience.
