Disposable armies

This is the case for all of the ensemble movies "“ whether it is the Chitauri or whether it is the zombies/whatever from Suicide Squad, we cannot get rid of them for good. I get it "“ the heroes must battle someone until they face the big baddie of the movie. And cannon fodder is thus essential. Not even Deadpool escaped this cliché, even if it played wonderfully in the end (spelling a name with dead bodies is always awesome).

And until the studios decide to have the teams face equally powerful villains, I don't see this changing. The Parademons will follow in the Justice League flick. And I can bet that Thanos will bring an army as well (as if he actually needs one).

As awesome as The Avengers was, the entire third act was a mess. Especially considering that Black Widow and Hawkeye can take on the same opponents as Hulk and Thor. It's even worse for Suicide Squad, which has even greater inconsistencies.

As said, unfortunately, I don't see the superhero genre getting rid of this cliché anytime soon.
