For Thor, Cap and Iron Man, each of their sequel movies has progressively made more money. The Third movie for each has been MASSIVE. Both Cap and Tony hit 1 Billion for their third film, but I don't think Thor is reaching that height. Right now he's at 738 Million so far which easily trumps the 644 from TDW. That being said, Cap's Trilogy is EASILY the best of the 3, as much as I like Ragnarok.
^Honestly Thor: Ragnarok could be my number one even right now because it's so fresh, and it's been awhile since WS or GotG. But that's my solid top 3 for MCU.
Agreed with CPT Space Bomb: Logan is my favorite comic book film of the year, but Ragnarok is the most fun I've had at the movies by far in 2017.
Yeah, it's a weird pattern I am noticing. 90% of the people I have spoken to about it enjoyed the film more on second viewing (as did I). I guess once you already know the main story, it gives you more time to appreciate all the other little things they threw in. On first viewing, I felt it was on par with GotG vol. 2, but now I think it's better.
