It is a hilarious comedy, and, at the same time, it is also an excellent James Bond movie. Like, 100%, a solid James Bond flick. Just minus James Bond and all the sexism, plus Melissa McCarthy and lots of funny. (Also Miranda Hart!)
It's got many different flavors of humor, and it's mostly not a satire/send-up of spy movies. It is an action movie, and has a lot of really good action in it. And pacing. And did I mention it's funny?
And stay through the credits! And pay attention to them! Because I want to be able to reference the jokes and have people cackle along with me!
