In remembrance of Stan "The Man" Lee and all of his great works, these are his movies in chronological order. These movies were not made in the correct order so this is the correct order it should be in. This follows the flow of all of the stories that end up meeting in the end. Each movie has one or more connections to the other movies. Little Easter eggs are hidden in each movie leading up to the other.
The first movie that should be watched is
Captain America: The First Avenger - This movie giving us the story of how it all began.
Iron Man
Iron Man 2
The Incredible Hulk
Thor
Avengers
Iron Man 3
Thor: The Dark World
Captain America: The Winter Soldier

Avengers: Age of Ultron
Ant-Man
Captain America: Civil War
Doctor Strange
Spider-Man: Homecoming
Black Panther
Thor: Ragnarok
Ant-Man and The Wasp
and the final movie to watch is

Watching all of these movies would take almost 18 hours. With the unnamed Avengers 4 movie debuting on May 3, 2019, there should be plenty of time to catch up with everything that has taken place.
