These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Rey Mysterio Jr
Fanon Discontinuity: His first World Heavyweight title run mainly due to that was the period where WWE was milking the late Eddie Guerrero's name for all it was worth. Not to mention they dropped "heavyweight" from the title's name for the duration of Mysterio's reign, as if no one would notice.
Fridge Brilliance: If Rey Mysterio's been hiding that knee brace under his pants for all these years, the 619 (Tiger feint kick, essentially a knee to the face) as a finishing move suddenly makes a lot of sense...
HSQ: Taken Up to Eleven in his first "I-Quit" match with Chavo Guerrero on Smack Down. And the biggest "holy shit" moment of the match was that Chavo actually won, by hanging Mysterio upside-down from the set and smashing his knee with a chair until Mysterioscreamed the words.
Only for a rather nasty case of History Repeats to come into play later on with Mysterio hanging Chavo upside down on a turnbuckle and doing the exact same thing to Chavo. Unsurprisingly, Chavo quit that time.
Too Good to Last: YMMV by miles on that one, but at one point, Rey actually managed to win the WWE championship. Almost the whole locker room was celebrating, until later on in the night... guess who got a title shot?
Vindicated by History: When WCW closed in 2001, then-WWF initially passed on Mysterio's contract because they had no interest in him. They changed their minds and hired him in 2002. Now he's a 3-time World Champion.
Win the Crowd: Not so much the crowd, but the fact that Rey has become World Champion makes this more of a corporate one. Due to his size, wrestling style and the fact he isn't a star "made" by WWE, Vince McMahon was reluctant to ever push Rey into the main event. The sheer quality of his matches and ability to get over with WWE's target demographic, however, eventually led to him becoming one of the company's biggest names and a consistent main eventer.
