Let’s be generous and call it “recycling” rather than self-plagiarizing. Does it bother you when you notice that writers are doing that?
John Shiban and Kim Manners were two of the most prolific writers for The X-Files and now both work on Supernatural writing and directing. And there are episodes that are lifted almost whole cloth from one series to another. I don’t mean that they’re just thematically similar (both shows had episodes about wendigo and so forth) but that they’re virtually the same scene by scene but they changed the setting and characters’ names (like some not very good fanfiction, actually).
Demons - X-Files season 4
Mulder wakes up one morning in a motel room with someone else’s blood all over him. When he calls Scully he finds out he’s been missing for several more days than he can remember.
Born Under A Bad Sign - Supernatural season 2
Sam contacts Dean after being missing for a week. When they reunite, Dean finds Sam covered in blood and with no recollection of what happened.
Monday - X-Files season 6
A woman is forced to relive the same day over and over as she tries to prevent Mulder and Scully from being killed by her boyfriend during a bank robbery attempt.
Mystery Spot - Supernatural season 3
Dean is killed after looking into a case about the disappearance of a man with Sam. The next morning, Sam is shocked to find Dean alive and is hit with the realization that he is reliving the day before over and over again.
Watch the pairs and you’ll have a stronger sense of deja-vu than Mulder does in Monday. I have a niggling feeling there’s one more pair of episodes like this, but I can’t think of what it is off the top of my head.
Anyway… what do you think about doing this sort of thing?
