This list includes everything in the MCU by Marvel Studios in the probably best watching order - based on original release dates (e.g. Daredevil was written to be released after Age of Ultron), knowledge which otherwise gets lost in the shuffle (e.g. to understand a certain part of the ending of "Captain America: The First Avenger" you need to have watched "Thor" first. Also, a certain method is mentioned in 2x03 of SHIELD, which has its origin in the later shown first Agent Carter season, etc.) and timeline (when it comes to Netflix shows, as their placement based solely on release dates makes things iffy),
The list does not include movies where the movie rights are somewhere else, like the older Spiderman movies, X-Men (and its spinoffs like Deadpool) or the Fantanstic Four. They are not part of the MCU.
