Spoilers I'm not a comic person and just generally read some quick little wikipedia info on characters I only vaguely recognize, so I'm not upset with who Taskmaster is because I only know him from stuff like MvC. With that said I think the film worked best in the first half with just non stop spy/action scenes. I got a little bored once they all met up and got to the red room, and the action scenes kind of took a dip as well as it got very over the top and was clearly going for the normal MCU ramp up the stakes astronomically high. I think it would have worked better going for more of the Jason Bourne route of a low stakes spy thriller but maybe I shouldn't be expecting anything like that.
