Short form: this would make an excellent double-feature with Spy (whose trailers did it a horrible disservice: contrary to what they’d have you believe, that movie is not about Melissa McCarthy’s character being incompetent. Quite the opposite, in fact.)
Longer form: I found this hugely entertaining. At a few points it veered toward humor a little too crude for my taste, but not too often and not too badly; it isn’t the type of film I’ve noticed more often lately, which seem to be out to prove that women can be as crass and awful as men. (There is a broad swath of modern comedy I do not like at all, regardless of the genders involved.) And there were multiple points along the way where I think you can tell the script was written at least partially by a woman; it isn’t impossible that a man could have thought up the joke about toxic shock syndrome, for example, but the odds that it would occur to him are much lower.
And holy god is this a movie about friendship and sisterhood. There’s romance, but much like Frozen, the emphasis is on the main female characters, who are sisters in all but blood. It’s about having someone who will go to Vienna with you on no notice at all because you need to deliver a macguffin left for you by your dead boyfriend who apparently worked for the CIA. It’s about having someone who will high-five you for your ability to apply your video game shooting skills to the spies who are trying to get that macguffin for themselves. It’s about having someone who knows all kinds of random and embarrassing things about you, and who will offer them up in a desperate bid to keep a psychotic ex-gymnast turned model turned assassin from torturing you.
It is very violent, and often on the crude side, and do not go watch this one for the plot. The macguffin is really just an excuse for people to run around in different European cities, and although the story nods vaguely in the direction of there being some kind of power struggle over it, you never learn the first bloody thing about the bad guys’ organization and the thing the magcuffin does gets mentioned precisely once. It is as cheesy as you would expect and I think the script is a little embarrassed by it. The actual point is the two main characters figuring out who to trust, and never having to question that the other one is at the top of that list.
If that sounds good to you, go watch it.
