After the movie is done do you usually stay behind and watch the end credits either at the theater or just watching it at home on a dvd or something? I only like to see the list of actors and characters they play but after that i switch away from it. Though beforehand i ask if there's going to be an after credits scene.
I don't usually do that unless something interesting is happening during the credits. For instance, when I saw 'Amy' two weeks ago, my family and I stayed during the credits because we wanted to listen to the song "Valerie". Something interesting has to be going on in order for me to stay put.
I do when I'm at the theatre, since it's like, proper etiquette.
However, I don't do it at home, unless the credits are done in an interesting way (ie. Silent Hill: Revelation) or have a song I like playing during the roll (ie. Hunchback of Notre Dame)
Like people said only for marvel because I know there's going to be another scene after the credits. For anything else no, as soon as those credits come up I'm getting up and leaving
