Watched quite a few matches yesterday when my internet died...
CM Punk vs Samoa Joe part 2: highly regarded as one of the best matches of the 2000s and deservedly so. They put on quite a show all the while Punk whispers sweet nothings into Joe's ear in rest holds.
Bret Hart vs Mr. Perfect from Summerslam 91. One of the more underrated matches around. To me this is the perfect match and shows how a match should be worked. Also the commentary is incredible with Monsoon, Heenan, and Piper. Cannot find youtube link for this match, it is probably on dailymotion though.
Misawa/Kobashi vs Kawada/Taue on 5/21/94. Two weeks before the famous 6/3/94 Kawada vs Misawa match Kawada and Taue go after Misawa and Kobashi's tag titles. It's not their 6/9/95 match but this also rightfully received 5*.
