Is Sonic and the Secret Rings any good?

I've played it for about 4 hours and it is definitely..unique. Controls are solid, but the camera perspectives do alter your assessment of distance and speed. I'd call it a minor gripe. Basically, no worse than the Super Mario 64 camera, but not as good as it could be. What really pisses me off is the voice acting...that alone should knock the game to at least a 9/10, even if everything else was perfect. I think it deserves better than a 6.9, but certaintly not a high 8 or a 9. 7.7-8.3 is about right so far, to me. A well meaning idiot bought me "Barnyard Animals" for the Wii recently, but since I knew it was shovelware, I never opened it. I simply took it to Walmart and exchanged it for Sonic free. This is normally the type of game I'd spend $35 on, but not $50. Because I knew I could get it for free though, I picked it up. I figure Sonic and some combination of SSX Blurr/Wii Play/Mario Party 8 will keep me busy until Super Paper Mario comes out.
