She-Ra was one of the shows that really affected me growing up. I always found the contrast of the first promo I saw and the actual show very interesting.
Here's the very foofy promo that aired to advertise the book series. This one features Heather O'Rourke from The Poltergeist films.
And here's the heavily Star Wars inspired movie that introduces the characters.
Gotta tell ya though, I probably would've watched the foofy version too ;-)
