I remember back in '89 when Batman came out,just about everybody was wearing a Batman shirt or reading a Bat-book.It bordered on fashionable.I think that was really the last time where a comic movie made a huge impact outside of comics & comic fans.I still remember an Entertainment Weekly segment discussing the movie & went into a comic shop to get a few words from the owner....& there he was...Comic Book Guy in all his fat,bearded,suspender-holding-up-the-pants wearing glory.Foaming at the mouth about how Spider-Man was gonna be the next big thing(he's about 13 years late but...),he really didn't paint a flattering view of fans.
The bad....I don't know.Superman IV really evoked the cheesiness to a point where reading Superman might not have been cool but then Byrne's revamp & the media coverage for that kinda overshadowed(thank Gob).
