Saw it. It's fun. Not particularly deep, and I wish there was more of a focus on McCarthy's relationship with Wiig. But the cast has great chemistry, especially Jones, Hemsworth, and McKinnon. My god is McKinnon great in this.
The third act feels a little stale at times-- an action scene feels kind of meh until McKinnon takes over, for instance-- but overall it's a lot of fizzy fun.
