Horrible watch, won't watch again, and can't recommend, even for younger audiences.
I have no idea how this thing got a sequel. It's supposed to be two parallel mob heist stories, but they don't really line up past there being a heist.
None of the characters are interesting or likeable, maybe the girl squirrel, the dog, and the mute rat but that's more because they are lovable stupid / naive. You're not supposed to still dislike the "heroes" at the end of the movie. The writing parts of this that are remotely interesting are too complex for kids to get and they don't pan out.
It's literally a lot of "squirrels like nuts", "squirrels try to get nuts", "humans don't like squirrels", repeat.
Anything endearing about this is more...
