Re: 5 things you want to see
1. Any cameo/mention/acknowledgement of Pym or the Pyms (because for some stupid reason they insist that he won't play a role.)
2. Any non-mutant origin, but an origin nonetheless for the Twins. I don't like ambiguous origins.
3. Avengers Tower in depth and in detail. With more shawarma-esque team break time moments.
4. Cap's Kooky Quartet moment. Where Cap/Hawkeye/Quicksilver/Scarlet Witch team up for some purpose.
5. Thor delivering final/fatal blows to Ultron.
