BORING : Kane vs Khali - last weeks beat the clock match.
Entertaining : hmmm...there is so many matches but first 2 comes to my mind is,
Samoa Joe vs Kurt Angle @ Genesis 2006 and HHH vs Stone Cold @ NWO 2001
Most boring: Trips vs Taker at wm27, damn, that was just dull. Other matches that are boring are matches with two big guys facing each other, like Kane vs Big Show, Kahli vs Big Show etc etc.
Most entertaining: HBK vs Taker wm25. That match was just awsome. Most recent match was actually Cena vs Lesnar, a great intense fight. before this years Mania I thought I could say Rock vs Cena, but sadly, it didnt really delivered. Hogan vs Rock was awsome just for the crowd, another similar match was Punk vs Cena at mitb last year.
