My 10 year old saw the preview for Guardians of the and wanted to see it. I think she liked the racoon and baby Groot. So I told her we could watch the first one. We did, and she liked it. So now I'm contemplating taking her through the rest of the MCU. I was thinking about starting with the Iron Man movies and then moving on to The Avengers and hitting Ant Man before coming back to try some of the darker / drier stuff like Captain America and Thor. Thoughts?
