well the old ones are too hard for me to decide, there are so many awsome ones! mankind and rock feud always had some great endings, and the HIAC HHH vs mankind when the ring broke, even triple HHH thought mankind died lol, the 3 stages of hell stone cold vs HHH, damn that is one of the best matches ive ever seen and the ending was awsome, no doubt WM 20, triple threat also had a great ending, the last match between raven and dreamer in ECW after a three year feud was awsome too, stone cold vs bret hart submission match at WM 13 i think was also incredible... but lets go to some recent matches i thought had great endings
RAW that 1 hour match between cena and HBK, i honestly didnt know who was gonna win since WWE kept letting cena beat every1, but man after HBK flipped out of the FU and hit that sweet chin music and just fell on him.. it was awsome, perfect counter
WM 22, triple threat for the WHC, i loved when rey won that match, and the way he pinned orton with that hurracurana was freakin perfect
WM 22 hardcore match between mick foley and edge,.. come on.. who didnt love that spear into the flaming table???
TLC match between edge and cena... sure it was way too predictable but it was still awsome
though one of the worse endings to a great match was rock vs stone cold WM 17, the match is a classic, 5 star no doubt, but the way it ended was so... i dont know.. poorly done.. i expected a more emotional ending, but o well..
