I have lots of things and ideas that would be elemental in the movie. Though, my POV is kind of a mixed of a positive.
The idea of Sonic being an alien is nothing anything too spiteful, given the fact that in Fleetway’s continuity, Mobius is millions and billions lightyears away from Earth. There’s even a storyline where Fleetway Amy and comic book exclusive character, Tekno the Canary traveled to Earth and many other planets/other time periods into (guess what?) a warp ring-esque gate called: The Eternity Ring.
So comparing it to the likes of The Smurfs and Alvin and the Chipmunks is a huge stretch. I got into a fight with a nobody who only do DeviantART stuff now and not Youtube anymore who expect this to be some kind of cinematic “timeless” masterpiece of fiction and complained that “it’s not too accurate to the games”. Like, majority of the DiC cartoons and both early American and European comics are literally very accurate to the games. I hate extremely overtly analytic critics like NC and ConfusedMatthew who overanalyzed entertainment in media.
Given the fact we have warp rings, I do have a hunch that we might also be seeing a possible Live Action depiction of the Special Zone. Though, I would love it, if it is an extremely Cool World-esque landscape with the first 3 Genesis Games’ versions of the Special Zones combined into one. Especially that headache-inducing one from the first game of the series. Rings and warping the user(s) to other dimensions is a concept that was a thing all the way since the 1st game. Though, it is shown that when given more rings, you could be transported to other dimensions/zones.
Given with this fact, with Baby Sonic (though it might be scrapped before the movie’s release given new changed scenes in the movie) I would like the idea of the denizens of Mobius or whatever they’re going to be calling it in the movie, are actually experimenting with the rings before they create the Star Posts. And the rings are either mystical, or artificially made as a prototype to warp other dimensions. So maybe Sonic’s parents might be scientists or Sonic was used as an unwilling guinea pig. I really like that idea!
It’s unknown as to how much/many characters are going to be in the movie. But given for the fact we have Sonic and Robotnik, I think we might get a quadrilogy of movies or a trilogy of the first 3/4 Genesis games with elements taken from the modern games. (Sonic 1,2,3K, and CD) One of the modern entites that will be in the movie from the games is the Military/Government (G.U.N.) But it’s unknown if they’ll be called that. Given the fact that Movie Robotnik works for them, it’s basically a parallel of Gerald Robotnik from SA2.
Given this, it might be assumed that only Tails, Knuckles, and Amy will be part of the movie universe. As well as Metal Sonic/or some kind of Robot Sonic doppelganger that they will be calling it in the movie. I really don’t know if they’ll get away with having the Death Egg in film given the fact that it’s the Death Star and Disney might sue…
I don’t know if majority of the badniks will be in the movie too, as we only have those odd Satam Spycam looking things. And those robotic car mobile robot Transformer things… but I’d want Metal to be in the movie universe.
I think the only characters that might be brought back full-form would have to be the Chaos. Given the fact that they’re practically pets. Though, I’d best thought that they originated in Sonic’s planet than being part in the planet. But unless they’re worshipped as idols or gods in Earth, (which would be taboo even for this movie’s standards and tone) connecting to Chaos. I really don’t want them to just clutter with all Sonic characters, otherwise, we will not have time to have development of them. Which is one of the reasons why these so called “Fans” annoy me with the whole movie being horrible without no other Sonic character than Sonic and Robotnik.
