Short version: …look, it was fine, okay?
Slightly longer version: pretty much the short version, with a bit of ‘THE MARVELS would have made a lot more money in 2020’ tacked on. It was all right. I’m not saying it was spectacular, because it wasn’t. The percentage of the population who watched two particular television series and the first movie is a lot lower than Marvel apparently thinks, and that’s going to hurt box office. And we’ve got superhero fatigue out the literal wazoo at this point.
But it was funny, and at its best when it was gonzo. I laughed. There were a reasonable number of moments where I laughed. The trick is not to take the movie seriously, and you’ll be all right.
