Yeah, Young Avengers would *definitely* work better as a TV show at some point in the future. Kamala might juuuuust be able to make it to Avengers proper in 2026, who knows? One thing is for sure, it's going to be East Coast Avengers all the way, in comic terms!
Regarding the multiverse, I more or less agree. They should have either run with it OR keep it pretty simple... and they have done neither. It's just complicated enough to confuse the mainstream audience without realizing the full potential of multiple realities or versions of characters in the same story lines.
I liked "What If", though. Very well done for what it is.
