Depends, Sonic has sort of gotten a new lease of life on those gimicky Wii games, like Olympics and Smash Bro's. And those games are fun, but that's probably more due to a lack of story. But I know my 6 year old cousin is a fan of Sonic now through them.
As for the actual main stream games. Well. They've realised that 3D sucks with Sonic and they put more 2D enviroments but that didn't work. They tried getting rid of as many of the neon woodland forest animals that tag along but that hasn't worked.
They've been doing a lot of stuff that hasn't worked (goose that layed the golden egg story) so I'd just suggest they either go back to the original idea's e.g fast hedgohog does 2D platform adventures, or accept that Sonic don't work no more.
Also, get proper writers for story and dialogue!
