I enjoyed the film for the most part. Some of the changes are sure, whatever. But the ending, and one major choice kinda just ruined it by the end for me. It was funny and had some cool action scenes, and the cameos were great. But all that got outshined for me by reading the book and having the ending so greatly changed, when the rest of the movie wasn't terribly changed.
Saw it last week. So many movies of recent are having the same kind of theme with comedy meets randomness. I saw this theme also in the movie, Everything Everywhere All At Once. I wander if they all got together and came up with the same ideas. That is to say it wasn't a bad film---deductive in placing all the clues together to find the mystery villain.
I saw it it's a good action movie, I had a good time.
