I'd recommend it myself, but I don't know if you'd like it, specifically.
The cartoon is quite a lot of fun, you kinda have to look past the fact they Simon Belmonted Knuckles. Then again, the dark brooding loner aspect of the character was getting tiresome, and Sonic Underground translated that into Knuckles being a little emo (I want to say the B word). I kinda like him being an egotistical lunkhead.
Seems like this game is unfinished and I heard that developers knew it was going to have things wrong with it and left. That sucks because this is the second time a company tried to launch a cartoon and tie in game where the game was looked down upon. The other being Pac-Man, and while the game play doesn't look great nor terrible, I give it credit for all the continuity the game has with the cartoon. Too bad they were too cheap to have the same already low priced Canadian voice actors for that one.
Now the third aspect is a comic book, which I unfortunately haven't picked up. I don't really plan to, unless I can get them cheaper, but they seem to be pretty funny from the previews.
