Another premier, so got in. This was a bit fuller than the previous one, but still not bursting.
I haven't seen the trailer, so no idea what is revealed. What we have here is that Kong find another layer to the Hollow Earth (...the planet has severe gravity problems...) and lo encounters a whole new villain to fight. In related plot, humans follow Kong and encounter something that I feel would have been set up differently in the previous movie had they known they were doing this. And Godzilla is hanging out.
Yeah, this is a Kong movie that guest stars other titans. The humans feel like "we have these actors who agreed to return for this movie, so we need a plot for them, as well as throwing in some other characters". We don't get the return of Millie Bobby Brown, but do get her sidekick the Conspiracy Wacko (who is less of a wacko in this). And Godzilla was also there...
The actors were fine, and not annoying unlike so often in the previous movies. (G-1 so much showed up how to do humans in a Godzilla movie.) There is a lot of time with Kong and Ko, and while the CGI worked, they simplified so much to make the basic story/emotions come across. [And, amusingly, a trailer for Kingdom of Planet of the Apes played before this!]
There's a few other comments I want to make, but for the sake of spoilers, I will resist.
It's fine, and better than previous entries, but I hope future movies aren't just "here's another generic villain" (although that does describe most movies).
