So yeah, most 3d Sonics sucked balls. Buuuuuuut... I actually really enjoyed Sonic and the Secret Rings on the Wii. No, seriously.
Yeah, the music was embarrasingly questionable, and the voice acting was atrocious (thankfully, you could replace the grating over-acted English with childish but less infuriating Japanese plus subtitles). And oh god, the menu system. Die. In. A. Fire. And the "story" (WHY?) was more of a mess than the first Mission:Impossible film. Sadly, these negatives were what the critics focussed on.
But apart from that it was a really good game. Getting all the bonuses was challenging but challenging in a way that was fun to play - you wanted to conquer that stage by improving your skill, not just for the sake of some crappy reward badge or achievement or whatnot. It had cheap shots, yeah, like the blind spot "killed by cactus" moment about an hour in that had a room full of SOBER people rolling on the floor laughing. But all these tropes were completely retro and keeping in theme with the original Sonic 2d games. Anyone who complained about these points yet defended the original games as still relevant today I feel is a hypocrite.
Most importantly, it had the speed from previous games -- plus some more once you got sufficiently into the game -- tight controls (backpedalling was weird but at least consistently so so you could learn it) and utterly fantastic graphics for the Wii, on par with Nintendo's 1st party titles, including rather unique art direction. No framerate probs whatsoever. Utilised the motion controls in an intuitive and constructive manner (sideways remote like a NES controller, tilt to sidestep, thrust forward to jump forward), whilst avoiding the mysterious uber-rapid battery drain that titles like Zelda suffered from. It was actually one of my favourite games for the Wii despite initially being an impulsive "I bet this'll be good for a laugh" purchase.
Even the multiplayer mode was incredibly enjoyable as it was basically Mario Party for griefers - the poor design and controls of half of the minigames was actually what made it great. In stark contrast, the other half tended to be superior to their Mario party equivalents. Go figure. Lots of fun if you're with the right group of mates who don't take shit seriously.
If you've got a Wii, and yearn for the oldschool style Sonics being faithfully reproduced in 3d, try to rent or borrow a copy of it. It (surprisingly!) may not disappoint.
