The Multiverse Saga for me has definitely been hit or miss but the Kang storyline, so far, has been a big hit. I understand that people felt let down by him being beat by Ant-Man but the whole purpose of the villain is that there are literally thousands of meaner versions of him lurking out there. Cut one head, and from it 10 more will spring. I feel that's the point they were trying to make (although it did feel like a letdown that there were no true consequences of such encounter with any of the characters). Scott should've died, and have a variant of him take over his roles as the "main universe" Ant-Man or something. They literally can do anything with their multiverse storytelling devices.
I really hope they don't ditch his storyline because they're invested so much into it (it's been years of teasing The Kang Dynasty and the big multiversal war). It's a shame about Majors, though, because I feel he's a pretty amazing actor and really brought the variants to life.
There are some pretty amazing actors that could take over, and I wouldn't mind! Any ideas?
