Only US wrestling? Well, that sucks.
The best thing I've seen this year is LA Park vs El Mesias (Hair vs Mask from TripleMania). Yup, Judas Mesias and LA Parka have had the best match this year.
As for the US...
1) Christian vs Randy Orton (Over The Limit)
The only good thing to come out of this shitty PPV. These guys have great chemistry with one another, and this was just another example of this (Their previous match on SD was pretty damn good too). Loved the nod to the finish of the first match with Christian going for the same move that cost him the title... And Orton decided to bust out the Billy Goat's Curse for some reason, so I can't complain >_>.
2) Smackdown's Elimination Chamber (EC 2011) AKA Mysterio kills himself for our enjoyment.
The match that made me care about Drew McIntyre, to be honest. Just great performances from everyone involved, with Rey once again stealing the show. Drew looked like a beast from head-butting the pod in anticipation, to throwing Rey like a lawn dart into one of the pods (Shades of Kevin Nash!), this SHOULD have been Drew's break-out performance, but it unfortunately lead to nothing... About the only bad thing about this match.
I'll add some more later, including a match from Superstars which featured... Chris Masters! Wait, wut?
