My "brief" thoughts:
Guerrero-Benoit was given a good 8-minutes, had a 100% clean ending, and was one of better pure wrestling TV matches in a while. Just two guys killing each other for fun. Awesome, awesome match.
Rock-Angle was fantastic too. I knew Angle wasn't winning, but when he kicked out of the Rock Bottom and Peoples Elbow, I thought for a second they might do something. Just a great match with a good mix of brawling and pure wrestling. Angle's new edge is neato, but what he's going to do for WrestleMania is beyond me. I like what Sven said earlier, I guess repeating what was said on LAW, and moving into Angle vs Benoit.
And, not to be outdone, Shane's return was perfect. He seemed to be really going to town on Vinny Mac and Regal and the crowd was popping huge.
Jericho vs RTC was also better than it had ANY right to be, Test looked good (And they're doing a GREAT job getting the big boot over as a killer finisher) and the opener was decent-to-good.
