Primarily, I just think it's a really good match. Some real cool spots with fun stuff mixed in. It's also nice and long really showcasing the talent of the wrestlers. Plus Sarah hadn't been on TV lately, just reappearing in the battle royal. I do think that for whatever reasons there are, that she works a less intense style in TNA. I would definitely like to see this side of her there.
I also know that CMLL isn't as widely exposed to the board members as WWE and TNA and that maybe a few readers would like to see something different or be turned on to something new.
More than anything I think it shows that women's matches can make for compelling television when given the chance, and that WWE could use the Divas as their most marketable asset rather than as bathroom breaks, afterthoughts or generic faces and bad soap opera characters.
Surprized this hasn't been talked about yet. Now on WWE.com, you can tune in to a simotanius webcast during RAW. Mostly behind the scenes stuff, and matches during the comercial breaks on USA. http://media.wwe.com/wwelive/live_300.
