A lot more enjoyable than I expected, especially because it had an "end of the world" climax where it felt like something was actually on the line, given how important the world and its history was to the Eternals. This movie still raises my usual Marvel complaints (it's a bit too long, the jokes get old, people turn into rubbery CGI doubles too often) but it works just fine, and "just fine" is the goalpost for these at this point.
