One of the movie recently saw at cinema. Despite already know it is commercial by product and try to introduce the character before put it inside Avengers together and show up in the coming End Game. But really, it a bit of after watch the movie, I thinking, actually without saw it I think will be just fine without impact on the overall watching experience for the coming Eng Game.
Fully understood paper based comics is sunset industry, and only way to make profit out of it is to make movie and make it more easy to be consume that way. So we got so many super heroes movie one after another, due to the reason maybe in the past those comics had the glory history in the past, but need some new way for package it and introduce into the market.
I would like to said the cross over with the Avengers or DC Justice League both is very successful marketing model, together is one good story. Standalone each had their own story can be tell. I saw synergy among that.
If you had yet watch the movie, personally I think no watch also no harm your coming end game experience. Nothing personal, just the story just no click at all.
