We are in my wheelhouse now that the focus is on Marvel movies. I've seen them all (except Ant Man cause busy and Hulk for obvious reasons). Ask me anything.
Quick handy lists for you guys.
Catastrophe's movies you need to see leading into Infinity War: (tried to put these in order but
)
1. Iron Man (prerequisite to watching any Marvel movie, really)
2. Avengers 1 (#2 tries to add story/buildup, but it's really not necessary with Civil War being what it is)
3. Captain America - Civil War
4. Guardians of the Galaxy (either one really; if you have to pick one, go with #2)
5. Dr. Strange
6. Thor Ragnarok (super fun movie)
7. OPTIONAL BUT RECOMMENDED - Spider Man Homecoming (the movie doesn't really provide any helpful backstory but it is great and really makes you like the character)
