I love the MCU.
I don't think most people truly appreciate just how good they have it these days as far as movies go.
I grew up in the late 1970's, and read comic books throughout the 1980's into the 1990's. This was a time when comic books were read for their stories and discussed with friends. Comics were not just bought, backed, and bagged as a potential future income source. I actually read hundreds of issues of Fantastic Four, The Avengers(East and West Coast), Uncanny X-Men, Excalibur, Spiderman, Thor, Iron Man, Captain America, and many, many more. I used to read every monthly column that Stan Lee would write, and I don't give a damn what some "woke" millenials think about him and his friendship with Jack Kirby or whoever else they want to feign indignity in the name of. There were some great stories in those old comic books, and I loved the good ones. Like Emperor Doom, the Infinity Saga, Secret Wars, Annihilus and the Negative Zone, the Evolutionary War... there's still so much untapped potential beyond those few.
Maybe it's because I've been a nerd for my entire life, but I can't help but shed a few tears while watching these films. Mostly it's the music which stirs old emotions of nostalgia, remembering that I never thought I'd get a chance to see this stuff done up right in a movie. I felt the same way about Lord of the Rings 20 years ago. I knew they didn't get the story verbatim, things were changed and some characters were left out or ommited entirely, but what they got right was better than I could have imagined! Things in the MCU are not exactly the same as the comics, nor should they be. It's a different format, it's a different time, and I'd rather go into a movie not knowing exactly how things are going to turn out than have a damned checklist making marks in the right or wrong column throughout the show.
I loved all of the Netflix Marvel shows, and the Runaways, and Cloak and Dagger, and I even liked the Inhumans(for what it was)!
I am by no means young, but I'm not elderly either. I saw the original Star Wars in the theaters the summer before my 4th birthday, and it blew my little mind. The music, the spectacle, the action and adventure, that movie was a paradigm shift in entertainment. However, this is only said to give you some perspective as to where I'm coming from and just how many movies I've watched throughout my life. I've watched "the greats", Kurosawa, Hitchcock, Scorcese, Kubrick, etc. Keep in mind that music, movies, books... ranking and rating these things is entirely subjective.
My favorite hero is whoever happens to be on-screen at the moment, I don't have a least favorite.
Same thing for favorite villain, and actor/actress.
My favorite movie is the only movie of its kind.
Nothing like it has ever existed in cinematic history, with 22 tie-in movies leading up to it, and it's doubtful that there will ever be another movie like it.
In my opinion, Averngers: Endgame is The Greatest Movie of All Time.
