Most of its attempts to connect through movies and make it feel like it's all been leading up to this are pretty sloppy. It still maintains that palpable tension and non-stop pace found in the rest of the films, but i can't help find a lot of the plot heavy scenes to be a little "key jingly" for my taste.
That being said this hits hard. While the physical connections to other films are pretty sloppy, the emotional and thematic ties are stronger than they've ever been. The stakes have never been higher and Ethan has never felt more like Spy Jesus.
