Spider-Man, I can understand, because it's probably different from what some people expect/want. There's definitely some Iron Man bias from me, and I'm sure that detracts from the movie for others. The twist of Vulture being the dad, and Holland's acting, makes the movie much better than Captain Marvel for me.
Even though I abhor some of the unnecessary comedy in Ragnarok, I find it very difficult not to love. And I hate the entirety of the pre-title movie. I cannot stand those first few minutes.
