I didn't know Sonic was in it at first, but when I saw him on a poster in the movie theatre I was instantly hooked it to. It was also based around a racing game for part of the movie as well which added on to that.
The movie was good because of the story. Not because of Sonic(Even if Sonic wasn't in it, the movie would have still be better). I liked the movie for the characters, and not cameos that only appear for a few seconds.
e-e No need to flip out. I'm a Sonic fan, and I can see WHY this guy doesn't like the group! It's full of mary-sues and whores. I'm still a fan of Sonic only because of the small group of people that aren't mary-sues and whores.
