So, what do you think of Undertaker vs Shawn Michaels feud overall (1997,1998, 2009-2010)?

All their fued were good. Undertaker and HBK have some special when they wrestle together. They always could put up a good match. Back in 1997 or 1998 when they had that Hell in a Cell match, it was excellent. One of the ONLY 5 stars match ever to happen in WWE. 11 years later, they got the match of the year for their match at Wrestlemania. What way to finish HBK's storied career off then to have the man who he put up his best matches against (Undertaker) retire him? They have yet ANOTHER good match at Wrestlemania 26.
