They've been hit or miss recently, there are some that are probably among the best and there are some that were made in a rush. It seems recently that the quality has picked up again. I'd say that #77 (aka as the Dream) is def one of the top 5.
The show lost its touch when he gave the rights to WWE. Ryder is a dumb fuck.
apart from some varying quality which is natural for such a long running show, and probably also has a lot to do with ryders wwe career going up and down (the show sucked when he was on raw a lot as it was basicly just recapping that) it hasnt changed since it became wwe official.
if anyone has any links to any boris alexiev (santino marrella in OVW) matches send me a pm!
