Interesting premise, painful execution The idea was interesting, but the execution was incredibly problematic. The first episode was the best attempt at it, one single change, one single choice, creates an alternate timeline and alternate story. Had every episode stuck to that structure it would likely have been much better and much more interesting. Instead, some of the timelines are a complete departure from the original (ex. Hope wasn't an agent pre-avengers therefore couldn't have been killed, Strange was too arrogant to love Christine pre-accident therefore wouldn't have had this dilemma). That was the first issue.
Second issue was the authors attempt to make the alternate protagonists better than the originals (possible exception, ep. 4). But Carter was better than Rogers (got to the Tesseract first), T'challa was better than Quill (peace and love baby) etc. Not sure if this was power creep or the needs to remake everything in a woke vein, but it was it just formulaic and made the series (in general) a yawn.
