A lot of similarities between this and The Monkey. Doesn’t go all-in on horror comedy, and also isn't funny enough or gruesome enough to be a standalone of any of those. The plot is half baked and super thin, and there’s a lack of relation or attachment to any of the characters.
If you saw the trailer, you saw the movie. Anything not in the trailer was just filler. But yeah, that’s basically it… bad humans try to exploit baby unicorn… parent unicorns retaliate.
Paul Rudd was miscast as a dad, and honestly seems like a pretty crappy dad to begin with. When they tried an emotional moment toward the end, it falls flat because you have absolutely no interest in his relationship with the daughter.
