My controversial Minecraft Movie opinion is that isekai could have worked for it, if they had just played it like a vanilla minecraft world. It’s even the game-movie most suited for an isekai storyline tbh.
A couple of kids wake up in a strange new place and have to figure out how to survive. And then, eventually, how to get back home. And this could take you all the way from punching a tree to killing the ender dragon, ending with The End Poem, which can be read aloud as it scrolls across the screen by all the weird helpful people the kids met along the way (steve, alex, mcyt cameos)
Also Steve isn’t white, the piglins aren’t evil or in the overworld, and the whole thing is animated. The kids are blocks in the block game and if you absolutely must have them be real people, have it be a split second of them waking up after the end poem
You could even start off with the quippy, flippant refusal to emotionally invest that all the cool kids are doing and gradually fade that out as the kids and the audience learn to care.
Address it even. Because caring about things is scary and its so much easier to be all nudge nudge wink wink but how sad to never be earnest or vulnerable? How very lonely that is.
