I'm up to giving them anyway :p

Way I see it? Postcredits stingers are at best useless and at worst cowardly. There is nothing that has been done after the credits that couldn't have been done the same or better within the body of the actual film.

The post credits scene is usually either some stupid extra scene that serves no purpose, or, since Marvel made it popular... A sequel hook.

For the extra pointless scene, my brother in christ if you couldn't figure out how to fit the scene into the movie it shouldn't exist. "murder your darlings" is writing 101.

For the sequel hook. Look. 1994's utterly terrible Mario movie had the testicles to put its sequel hook IN the movie itself instead of concealing it after five minutes of scrolly letters. If that piece of cheesy bullshit has the courage to hook its own sequel, then hiding your sequel hook after the credits is total lack of confidence. If Microsoft Edge can ask you if it can become your default browser, a movie director should have the confidence to put their sequel hook in the text of the actual movie.

Also on a more personal note: when a movie ends I am usually kinda sorta in need of going to the bathroom? It's been 2 hours and I drink a lot of liquid? I don't wanna be stuck in the theatre for another five minutes watching... Not the movie because that's over. Lest I miss the important thing they hid after the credits.
