Weak characterization. Overuse of computer graphics. Masks with goggles that don't fit the eyes of the character wearing it. The scene with Tom Hanks was ripped straight from Top Secret, minus a tape measure. The weakest writing I've seen in the MCU, second only to She-hulk.
This movie was made for people who like to watch helmets flip, but not be worn. For people who like to go to buffets only for the croutons at the salad bar. For people who like characters to be built up to as being all-powerful, but then be average when the fighting actually happens. For people who like black villains and white saviors. For people who like to laugh at bald guys for having weird body parts. In short, something I would've written in 8th grade.
Gave it an extra star because I'm sure there are still people like that, and I'm just not the target audience.
