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.
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.
Rom-Com? Heist movie?
Heist might make sense.
The trajectory could be something like survive -> kick ass -> pulled back in at a disadvantage? Maybe.
I felt the third Alien film actually made a pretty good punt at this; it's not a perfect film without its issues, but I rather like it. The "female lands on abandoned prison planet with a bunch of violent criminals" setting was a good direction to go in after the first two films. It would have been better if they had focused more on the prisoners and such and less on the xenomorph running after Ripley (especially in the second half). In spite of the problems, I still like it more than Cameron's Aliens (which was certainly not a bad film, but also suffered from some issues IMO).
A problem with "big franchises" type of movies is that studio people with seemingly no sense of what makes movie great get involved and make things hard for people who want to do anything different that could make a sequel work. "People paid for aliens chasing Ripley in the previously films, so we must have more of that!" I have no problems they're focused on their investment and money, but it never seizes to amaze me how poorly these people sometimes seem to understand their market.
The first movie in each case is horror, the monster is invincible and the hero is super weak, just trying to survive. By the end, the main character has survived and is now a certified badass. There’s no way to make a horror movie sequel without resetting the main character’s development. So instead, they made action movies, which was the perfect decision.
This is also why there couldn’t be a good third movie, there’s nowhere natural to go after action.
Maybe one could slip a disaster movie in between the horror and the action…
