Let me explain: part of why I like Evil Dead 2 so much is because it does a great job of walking the line between "horror" and "comedy". At some parts it's pretty goofy, but always in a way that kind of feels like it could plausibly be in a regular horror movie. Stuff like the moose head laughing, or Ash cutting off his hand and replacing it with a chainsaw are silly, and even slapsticky, but still kind of works in the tone of a "regular" horror movie.
Army of Darkness on the other hand is basically a just a comedy. It has no pretense of being anything else, and there's nothing wrong with that at all, but a part of me wonders what it would have been like if they had kind of kept the goofiness into "potentially plausible in an action movie" territory.
I really can't imagine what else one might argue.
I didn't agree with him.
There’s a strong parody element to the series, Ash is basically an idiot so it isn’t that annoying/unexpected to have him redo some character development. Oh he learned nothing in the previous movies? That scans.
It also manages to continue raising the stakes by shifting to a new genre. In this case, a sort of weird… fantasy/sword-and-sorcery/post-apocalyptic(?) universe. It confronts the protagonist with a new type of challenge so it doesn’t feel like a re-do.
Though, I guess you could argue that Evil Dead 2 is much more of a "comedy slapstick remake" of the first one than a sequel.
