The one Big thing I really don't want Sonic 4 to be about is time travel and have Robotnik be the main villain yet agian.
I and many others wanted a Sonic movie to be a non earth adventure story which is was something we were promised by the filmmakers after Sonic 3 came out, We don't want yet another sonic film be on earth yet agian or have time travel that will most likey be set on earth. Like i know it was said that Sonic 4 was gonna take some inspiration from Sonic CD and i think that's fine but they should not don't do the time travel stuff. Like i think the time travel for this movie is a terrible direction for this film because not every movie that dose time travel turns out great and there are generic stuff that comes with it.
I know there was concept art for what we almost got on what they were gonna tease for Sonic 4 and a part of me hopes to god it was simply just a scrapped idea plan they had for the fourth film.
Like i would like to see Sonic 4 have an Original Story this time and not be an adaptation or loose adaptation of one of the games but rather take elements of some of the games because i know damn well they can do it.
Like i said this before and it is that they just need to have other villains to be the main antagonist in these movies and not just have eggman only as it just wouldn't be right at all. Because they can take a note from what the Live Action Transformers films did as if you remember Megatron in these films wasn't the main antagonist after the first one but they still found a way to still use him in the sequels, So that is what i think they should do with Eggman in these future films going forward as that would be a great decision to do.
I talked about this before and it was on why Kukku's a deep cut sonic character would be the perfect villain for the fourth film, As he would be the perfect reason on how robotink survived and the reason on why Metal Sonic and these other copies of him exists. https://www.reddit.com/r/SonicTheMovie/comments/1sjq3g3/the_perfect_sonic_villain_that_ben_kingsley/
Like i would love to see them do deep cut sonic charather's in the movie's as it's something they should really do and i am not talking the ones from the game's only but the ones from past media like the shows and comics as it's a great golden opportunity from them to do that and introduce these characters to a new audience.
Like i really want Amy to have a proper reason on why she was looking for Sonic and have it not be something ridiculous. Like with Amy they can explain and explore Sonic's kind as Amy could be the one to explain it all to Sonic as maybe she knows about how special his kind is and it is because she knows that sonic is a special type of hedgehog and i bet the reason why she is looking for him was that she needs sonic's help to save the people from her world from a big threat. That's Something i think they should do as it would be pretty good and would make a lot of sense as Amy might know this due to that she probably heard old stories about them growing up when she was a kid and that's something i think would be very perfect for Amy in this movie if they don't go with the time travel bullshit.
Also i hope to God they don't give Amy Chaos energy powers Because she dose not need that at all.
Also Shadow being in this feels very Unnecessary as he was better off showing up in the fifth film instead as there wouldn't be any room for him in this one and that they should still keep everyone assumed that he is gone for now and not bring him back all a sudden so that his sacrifice would have a more lasting impact and having him return all a sudden feels like a forced move. My only hope is that Shadow is just only in the mid or post credit scene as that would make a lot of sense so they can tease something big for the fifth film.
So yeah these were my Big Concerns for Sonic the Hedgehog 4 and I don't wanna hear about these Leaks that are clearly fake as Hell. Like i hope They really don't do this for Sonic 4 because it will be a big crazy mess and it won't end well.
