I started a Wrestling Rewatch a few years ago now, starting back on the first Nitro. I'm currently up to October 2001, but I've only just started to blog the Rewatch.

I know of a few other blogs that have been recapping/reviewing WCW from the 90s, I'll share them later when I find their bookmarks.
