I actually thought Del Rio/Cena in the broken ring was a really fun match. Didn't like the Punk/Trips vs Awesome Truth match but the opening tag kinda owned. I remember liking Rhodes/Orton but not nearly as much as their no dq match from SD in November. Show/Henry was fun as well.
I don't remember Vengeance 2011 too well since I was completely beat and about to fall asleep when I watched it. But from what I remember:
Orton/Cody - ***1/4 (Not bad but I think they had a match on Smackdown which I enjoyed more)
HHH/Punk vs Moz/Truth - ** (didn't like it and I remember the bitching around here over Punk taking the pin "ZOMG CRIPPLE H BURIEZ PUNK!!!!")
Henry/Show - *** (Not as good as Survivor Series but still okay and the ring-break was pretty cool)
ADR/Cena - ***1/2 (Was good and pretty enjoyable. Plus I like how Cena STILL found a way to perform the 5 moves of doom. Got better when they went around the arena, though. Didn't make much sense for the Moz/Truth interference even though I understand what it set-up. Just hate how Moz/Truth got such a push as a team then when Truth got suspended, both turned to jobbers by early 2012.)
