I like to think of Boom like I do with Megaman Battle Network.
Does it have Megaman characters to a degree? Yes. Is it the Mega Man that started the series and keeps the same game play? Not really. The only difference here is I actually like BN to a degree, while I can't for Boom.
People really like to rip into the games Ken Pontac and Warren Graff wrote the stories for (Colors, Generations, Lost World are the main ones) and now I'm starting to see why. Classic Sonic is Classic Sonic, it aimed to create a different gaming experience while earnestly hoping it would make the creators a shit load of money despite the main character being based off of a Western pop singer, then US senator, and a Christmas staple for Western world children. As much as I don't like the Adventure era games, I give them credit for trying to work with something different and create something that many people fondly enjoy and appreciate. Technology was new, they couldn't depend on simple story lines anymore, and worked with what they had. Once we hit the era of Sonic 06 and games before Colors, it was a huge change and experimental phase. With the exception of that game, people have hit or miss feelings towards them.
Pontiac and Graff started introducing a lot of writing and jokes that became prevalent in the current games' humor. Sonic breaking the 4th wall, the line "No copyright law in the universe is going to stop me!", the robots making frequent cracks at Eggman's expense are the main examples in Colors. Idk what happened with Generations because the writing for that seemed like P&G were watched like hawks and had to undergo frequent script revisions. Lost World's story has several criticisms that are far too many that are worth typing out, but it follows in a few nonsensical jokes, bland villains, and something that feels like it belongs more in fanfiction than not.
P&G have tapped into a humor that seems to attract a different fanbase and mentality. What's come off as silly one liners has snowballed into the social media accounts screaming GOTTA GO FAST every 10 minutes and Eggman proclaiming how Shadow is the 2nd most popular character in Sonic canon...in the cartoon meant to be one of the funniest jokes in the finale.
There's just no integrity at all here. If you're going to poke fun at yourself, have some dignity for yourself. As much as people trash on Teen Titans Go, for the few self referring jokes I've seen back to the classic cartoon or other media, I give it credit for balancing it with its original writing. It doesn't use "WE USED TO HAVE A BETTER SHOW SO MANY YEARS AGO" every episode. It doesn't use "Please make and sign an Internet petition to keep the series with the series with the same 8 characters and 5 locations going" as a clincher. It also tries to keep itself unique, and that is something I fervently believe most people will agree with me on, regardless of your views on TTG.
I've thought about this a lot because I used to be one of those "Sonic is dead" people. Now I just watch the series run that marathon with their legs asleep and wobbling like fresh jello because there are some good ideas still coming out. They're just mired in uninspired humor that's been stale for a few years now.
