Before Infinity War, everyone should totally have seen Captain America 1, Iron Man 1, Thor 1, Avengers, Guardians of the Galaxy 1, Captain America 2, Captain America 3, Guardians of the Galaxy 2, and Thor 3.

Ironman 2 is optional just for world building and intro to Black Widow. Avengers 2 I think is optional, you will miss out on some important infinity stone action and intro to Vision and Scarlet Witch, but you get enough time with them in Cap 3 that I don't think it is seriously detrimental. If Avengers 2 was a much better movie I would put it on the essentials list.

You can Skip Thor 2. You miss out on the Power stone being given to the Collector and Loki replacing Odin, but that is about it.

Black Panther is skippable, you get enough about him in Cap 3 and you know Cap is his friend by the end. It makes the return to Wakanda more exciting for sure but thats about it.

Dr. Strange is skippable. All you need to know is he is super magic dude, and he has the Time Gem.

Spider-Man homecoming is skippable. It is a good movie and definitely builds Peter up more, but like Dr. Strange and black panther, they just aren't important enough in 'The Avengers" mythos that you need to see a whole movie starring them to know what the character dynamics are in Infinity War.

You can completely skip incredible Hulk, both Ant-Mans, and Iron Man 3, in fact it makes Tony look like an asshole how he quits being Iron Man for the 3rd time or whatever.
