Like your entire statement makes no sense.
" why are the characters they wrote the dialogue for in the show they wrote the dialogue for"
... What? Thats not a criticism, like sonic boom deserves a lot of it. But what you are saying isn't even a criticism, you just said " why does this tv show have to sonic in it" Why does anything have to have anything in it. What are you even saying
You're misreading my post. They didn't make the show for Sonic characters. They made a show with generic characters/situations and gave it a Sonic coat of paint. Without a base to juxtapose the wackiness to the use of the IP feels misplaced. The specialness of it being related to Sonic is completely lost. Similar to how the games don't play anything like a Sonic game yet use the Sonic IP. They could have just made a new IP.
