What movies and American TV shows can use the principle of cooperation to write papers?
The film "The Avengers" series and the American drama "Agents of SHIELD"
The plot of S.H.I.E.L.D. agents connects Captain America 2 once and The Avengers 2 once. If you don't watch the movie, the plot of S.H.I.E.L.D. agents can't be linked. Can it be regarded as a "button" left by American TV dramas for movies?
