I just saw Godzilla x Kong: The New Empire. It's pretty good. Lots of kaiju fight scenes, lots of fan service. Despite the title, this is very much a Kong movie, not a Godzilla movie, although whenever Godzilla does show up, he tends to steal the scene.
There are a lot of fight scenes in this movie, more than any of the previous Monsterverse films had, and most of the fights involve Kong (he's involved in 7 different fight scenes). Godzilla does get a few fight scenes of his own, but the ones that don't involve Kong are rather short and consist of him killing his opponents almost immediately. The only fight scenes with Godzilla that aren't short curb stomps are the ones where Kong is also fighting.
I will complain that I hate Godzilla's new look. They overdid it with thinning him down, to the point that it looks like a huge chunk is missing from his torso. The elbow blades and thagomizer feel like someone was trying too hard to make his new form feel cool, which isn't helped by the fact that he never actually utilizes these new weapons. I'm not a fan of the pink coloring either, but that I can at least tolerate, especially since they had a good reason for it: to make him easier to differentiate in fight scenes from Shimo. But perhaps the biggest thing I dislike about Godzilla's evolved form is that it doesn't actually seem stronger than he was before. Oh, they add more special effects than they did before, especially when he's using his atomic breath, but said atomic breath does not actually seem more effective than it was before. Likewise, we don't see any feats of speed or strength that dramatically outperform what we already saw him doing. It rather feels like Evolved Godzilla was thrown in entirely because Kong got a (significantly more justified by the plot) power up.
The human characters are much better than they were in Godzilla vs. Kong, largely because they dropped the more obnoxious ones while keeping the ones that were well recieved. They do start pushing teenage drama with Jia, but it's significantly less obnoxious than what we got with Madison in the previous movie, and they drop it almost immediately as the plot starts. And regardless, the movie focuses more on Kong than them.
Overall, Godzilla x Kong: The New Empire is a very good action movie, even if it would have been more honest to title it "Kong: The New Empire."
