Sure..ish. The level of arbitrariness for superhero power level is a gradient.So basically like nearly every other superhero/villain ever?
It goes from "Power level doesn't change much and/or such changes are well justified...to...Power levels fluctuate significantly with little or no explanation"
In this movie, it felt to me like the latter.
Ikaris has deadly eyebeams..except sometimes they aren't that deadly. Some of the characters seem like they're noncombatants.. except that they shrug off deadly eyebeams, or solo the "strongest" member of the team. A characters gets stabbed and we're meant to think that means anything, except that it doesn't seem to, yet Mr. Shrugsoffeyebeams hits Stabbyperson in the head with a rock and Stabbyperson is out of the fight.
No explanation, no justification, no red or yellow kryptonite or anything. Just a "yeah that all happened. Trust us this really is coherent. We promise."
