As with any superhero movie, whether it’s Marvel or DC, you’re right to wonder, “Should I stick around after the movie for a post-credits scene?” The whole post-credits trend started when 2008’s Ironman teased The Avengers after the credits stopped rolling. After that, almost every Marvel movie has teased fans about an upcoming film. DC just recently started to experiment with the formula. Only Suicide Squad, Justice League, Aquaman, and Shazam! have post-credits scenes — so far.
