whole plot of Ego impregnating every living creature just so he can turn every planet like him.
I would have wanted maybe a SHIELD quinjet hovering over that Ego lava just like the Xmen's Blackbird showing up in one episode of the 90's Fantastic Four. That's a missed opportunity.
Also this version of Mantis is sadly disappointing and they made her look like an idiot. She's not as cool as her original comic book version whose a pyrokinetic and can kick Karnak's butt.
I can't believe they managed to put David Hasseloff there.
