I understand but disagree with the feeling out of the power levels. If they wanted, they could show the true power levels. I thinks its done so the other characters are not overwhelmed. When I see characters that don't have any powers (Black Widow, Black Panther) hopping around like Spiderman, I get aggravated. But I am also aggravated when low-end characters, like Captain America, are shown like they are almost Hulk/Thor level.
Marvfel needs to rewally define their top tiers, as DC did with Superman in latest JLA movie.
Wonder how they will handle Thor/Hulk fighting Thanos?
