Luke Skywalker (Star Wars: The Last Jedi)

Luke Skywalker is the staple character of the nine Star Wars films. Ranging from being a baby in the Prequel Trilogy, to the icon everyone knew in the Original Trilogy, to what is effectively a grumpy old man. He was flanderized to death.

Why He Severly Lost His Charm
NOTE: This will focus on how he was butchered since Star Wars VIII: The Last Jedi.
 * 1) As mentioned above, he is extremely out of character in this film.
 * 2) *Rather than helping Rey with her training, he nearly refused.
 * 3) Usually, you saw Luke Skywalker be optimistic, which is what a Jedi represents; regards of what they are (i.e. Yoda was older, and he was still optimistic).
 * 4) *In fact, Luke Skywalker can be compared to Superman (DCEU) very easily! Both were iconic heroes who were flanderized from being optimistic, yet still heroic to being grumpy and showing negativity all the time. The only difference is that the former aged, and the latter was always a young man in their respective cases.
 * 5) When he was handed his lightsaber by Rey, he foolishly threw it right off the cliff.
 * 6) He didn't bother remembering Leia Organa, Han Solo, Chewbacca, C-3PO, and R2-D2.
 * 7) There was a disturbing moment when he was milking aliens just for something to drink.
 * 8) Luke Skywalker was supposed to represent hope, and in fact, Star Wars IV: A New Hope was referring to Luke Skywalker himself, which is an emotion about showing optimism, positivity, and not giving up even when it seems like it's always lost.
 * 9) When he faced his nephew Kylo Ren, he told him to die, taunted him, and humiliated him as opposed to what he did in Star Wars VI: Return of the Jedi where he told Darth Vader (Who was the most evil guy) that there was still good in him!
 * 10) He died at the end with no proper explanation.
 * 11) Luke Skywalker was flanderized to the point that even Mark Hamill himself said that the character WASN'T Luke Skywalker at all!
