All Marvel movies are interesting and powerful in my eyes but I don't have a favourite among them. I can rewatch any movie that's interesting to me many times that I want. Check these ones, 'The incredible hulk, Thor, Captain America'.
X-Men did a great job too like X-Men: Dark phoenix, X-Men: Apocalypse and the new mutants.
X-Men are my favorite and the ones I've probably seen multiple times the most. Second up is The Avengers. I like it when the superheroes form together to create an alliance. Also, Wolverine is my favorite superhero.
Eternals. Because it is the most different. I finally found MY corner of the MCU. I know it's not popular but I don’t care. I hope Chloe would go ham on the sequel and she should’ve gone full-on biblical. This movie combined my love for superheroes/marvel and movies of the style. It’s the prettiest, most profound Marvel movie to me and I love every single second of it. So intricate, complex, rich and oh-so emotional. The seriousness and the quietness combined with that epic scale make it such a special entry.
I like the X-Men movies the most (if I am forced to pick something). Now, there are a lot of movies that are good and I enjoy them. But I like the X-Men and I'm a fan of them, even if I haven't read the comics.
