We always do this for Star Wars, but never for Disney's other soulless cashcow. Let's begin:
18. Doctor Strange (2016)
This one is easily my least favorite. Because as the 14th entry in the series, it takes all the criticisms about the franchise and doesn't even try to subvert them. Boring, minimalist plot ✓. Forgettable, wasted villain ✓. McGuffin plot device ✓. Female lead that adds nothing to the story ✓. And the humor was the most shoe-horned and unfunny in the entire franchise.
17. Thor: The Dark World (2013)
Generally agreed to be a franchise low. This is the first movie I walked out of thinking they didn't even try.
16. Guardians of the Galaxy Vol. 2 (2017)
I think I lost interest and quit paying attention at some point during the third act.
15. Thor (2011)
Out of all the movies in the series, this is the one that comes closest to not working for me. Nothing in this movie feels earned, including Thor's character growth and falling in love with Natalie Portman. Also the movie takes itself way too seriously with this grandiose sense and everybody overacting.
14. Iron Man 3 (2013)
This movie would probably be terrible without RDJ. I appreciate that Black didn't just want Tony to fight another guy in a robot suit, but the fire people plot and Guy Pearce's character were pretty dumb. I also like how the ending is completely ignored in other movies.
13. Iron Man 2 (2010)
A lot of people point to this one when talking about the worst MCU movies, but I think it's fine... I get all the criticisms it gets but I think they make it work better than people give the movie credit for.
12. Thor: Ragnarok (2017)
I think more people need to give this one a rewatch. If not for Black Panther, I would say it is easily the most overrated movie in the franchise. The entire Asgard storyline fell flat for me and the Sakaar one wasn't much better. Still was pretty funny and well acted with some interesting new characters.
11. Ant Man (2015)
I had a good time with this one. The humor works because they were smart enough to make the stakes low. Paul Rudd was a good choice for this type of character they were going for.
10. Guardians of the Galaxy (2014)
Also pretty overrated. I liked it and was surprised by it, but sometimes I feel like people are watching a different movie than me when talking about this.
9. Black Panther (2018)
Decent origin story and I respect that it doesn't go the route of "ebin comedy movie because we don't have faith in the story". Fuck everyone that says it's the best though.
8. Captain America: The First Avenger (2011)
Same as above. I liked the respect for the character and it works well tonally compared to other phase one movies.
7. Avengers: Age of Ultron (2015)
I guess I liked this more than most people. Ultron was weak and I don't like the way Joss basically writes every character the same way except for Steve. Still thought all the moments with the team together were gold.
6. Spider-Man: Homecoming (2017)
Same as Ant Man. I thought this was the funniest in the franchise and they nailed the character imo. Vulture was also a good villain. Probably better than Loki.
5. Captain America: The Winter Soldier (2014)
I've been told I have this one too low on my list, but at the end of the day it just feels like another phase two filler movie. Still is pretty much the best filler movie it can be.
4. Captain America: Civil War (2016)
I loved this movie when I first saw it but the story is kind of weak and the villain's plan is convoluted and nonsensical. I still feel like the Russo's direction and tone really elevate it and the way they juggle all the characters so well was a surprise. It still feels like they were holding back, and after watching IW, the movie lacks much consequence.
3. Iron Man (2008)
Probably the best in terms of structure and tone. This was a time before they had to worry about franchise building and whatnot so we just got a really solid origin story and nothing else.
2. The Avengers (2012)
I mainly rank this so high because everyone said it would be impossible, and they made it look easy. Joss's dialogue kind of bothers me and it was the first movie to start messing with the tone but these are mostly nitpicks.
1. Avengers: Infinity War (2018)
I knew this was my favorite right after I saw it and still think it is. They said they were going to deliver on 10 years of build up and they really did. It honestly feels like they setup all these characters and movies just to reach this point where they could have a clusterfuck of characters fight Thanos like in the comics.
Didn't include Hulk because I don't think I've seen it since 2008.
