Why was Sonic Lost World reviewed so poorly??

I'm a fan of the original Sonic games and i really like Lost World, it not perfect but a step in the right direction if you ask me and prefer it to colours.
I think people dont like it because it looks more cartoony and didn't give the time to get used to the controls and the game does take a bit of practice to become good, i also think people think it's trying to be a Mario Galaxy which is not a bad thing.

Sonic games were about platforming more than speed which this game brings back to the series, and allows three different speeds to allow exploration or to speed through the level in spin dash which feels good once you master it, i believe before it came out IGN praised the game then when released did a complete u-turn.

What's the 3D to 2D level ratio? I'm only interested in the 2D levels, and the ones I saw in the previews looked great... but I dread going through the 3D races just to play some good old 2D Sonic.
