I have watched the first episode of Neon Genesis Evangelion and at the end, after the credits, there was a short teaser of the next episode, ended with the sentence:
Tune in next time for lots more fan service!
I have watched much more American tvTV shows and movies than anime, so for me, the word "fanservice" has more bad associations, like some unnecessary things, not connected to the plot. So if fanservice is mentioned in a teaser, does it mean something else in anime, or do people watching anime like fanservice rather than looking down on it?
