Metro aside, windows 8 has some nice updates and added in features.
If you don't like metro I strongly suggest these programs to give you the start menu back in Windows 8:
Start Is Back:
http://www.startisback.com/
Start8:
http://www.stardock.com/products/start8/
Start Is Back is a little faster and more responsive. But Start8 Is a little more customizable, and has a few extra features.
