No. I'm not kidding. Sonic the Hedgehog CAN look good in live action, and the link below proves it.

This is a Sonic the Hedgehog fan film produced by Blue Core Studios. The film has Jaleel White voicing Sonic, though I'm pretty sure Sonic's voicing is just voice takes from White's Sonic voice from the 90's cartoons. It acts as any traditional Sonic the Hedgehog scenario; Robotnik want's to rule the world and Sonic has to stop him. However, Tails isn't by his side in this. In fact, no one is. It's just the blue blur by himself. Anyways, this film came out early this year in January, and it already has 1 million+ views under it's belt. It's that good. I still wouldn't say it's better than the Sonic anime film that came out in 1999, but I still think this was 20 minutes well spent.
