Making the premise "An overblown modern reboot of Rescue Rangers! Isn't that a bit silly?" immediately underscores your thesis more than "An overblown modern reboot of [property we made up as an proxy for trends you hopefully recognize]! Isn't that a bit silly?"
It also means I have zero desire to see this thing and am actively repelled and annoyed by it. So what's the tradeoff there? The same way someone that has zero attachment to Thundercats like Wagomu can love Thundercats Roar for its comedy and fluid animation and everyone else here absolutely hated it for its character designs and seeming hatred of the source material. .
Roger Rabbit (who is in this trailer!) proves that it works JUST FINE to make up a new proxy character. So does Wreck it Ralph.
Either of those films could have easily been with existing characters, especially since they had cameo co-stars throughout, but as its own thing it still makes all the same jokes but without shoehorning in and messing an older property up to do it, and in the course of it makes its own new brand and ideas and freedom to go different places.
Saying that actual IPs would be off-limits for a project like this because they would be "messed with" or "tarnished" is just so stifling, and limiting, and hard-gates what you are """Allowed""" to do with any existing brand. New takes don't ALWAYS work, but a "bad" new take - or a take one personally dislikes - on an IP is totally cool, because otherwise you'd never get a "good" new take on an IP that you personally like.
You sort of have a point, given that Rescue Rangers itself was a crazy new take on the old Chip and Dale characters in the first place, It was a new thing for Chip and Dale. But Rescue Rangers itself is its own thing that worked. If this was just a Chip and Dale movie, fine, whatever. it can be forgettable just like Rocky and Bullwinkle or Fat Albert movies. But its a Rescue Rangers movie with specific iconography and characters to it. The first time this IP has been touched in decades, and probably the only time it'll ever be revisited because this is its one chance to prove itself as something still viable or worthwhile.
If something is trying to at least keep the spirit of the old thing while taking it in a different misguided direction I don't mind so much. Like the new Ninja Turtles cartoon where I hate the character designs, or any number of Transformers reboots or every new stab at Looney Tunes.
Sonic the Hedgehog has had six different cartoons now, all wildly, WILDLY different. I'm only attached to one of them, the one that took it seriously. But every single one of them stems from a desire to represent the hero character and his friends from the games, and even though the tones and even premises are radically different, they all manage the spirit of that. I actually watched all of Sonic Boom recently and it was fine. I didn't love it but it was fine.
But when you're doing something that has nothing to do with the existing brand aside from slapping the name on it, when you're making it SO wildly different that it's basically unrecognizable, then what's the point? If you aren't trying to capture some of what people originally loved, then why bother?
Live action Cowboy Bebop was a trainwreck, but their hearts and desire to do credit to the original were palpable, and you can see that they were close to having something good. The talent wasn't quite there to pull it off, but it wasn't just a soul-less cash grab. Meanwhile live action Dragonball movie that put Goku in high school and was written by people who admitted afterwards they'd literally never even looked at the source material? WHere they were ONLY using the name to make a quick buck?
