You are insane if you rated this movie badly. It is a romcom action movie, of course some is predictable, of course it doesn't have great depth as a storyline. But it is stunning, great fun, some hits and misses, but a love song to the stunt people that make movie magic happen.
Enjoy it for what it is, not for what you expect it to be. A good movie, a lot of fun, a few funny moments, cast is just so good with amazing comedic timing (which works for me personally).
And if all this won't convince you, just watch it for the unicorn scenes short but sweet (you will know it when you see it ๐คฃ๐คฃ).
