Fan Service Continues
In anime and manga any material added or adjusted to please the audience intentionally is clarified as Fan Service. In the weird cultural differences between the Western world and the Japanese, fan service could even mean about having a long shot of a woman's body and/or generally gratuitous nudity. But it's not just about that. Prolonged scenes, extra violence, references to other shows are also deemed as fan service. But what is this term I've been throwing at your face actually about?
It is about servicing the fans, if you will, providing the audience with the premise that was initially hinted at or directly promised, or somewhere in the process deeply desired. For its about giving your fanbase, regardless of size, what they want, to put it bluntly. As it has been said before, it could be fixing an annoying issue, fixing a crash, it could be adding content, adjusting previously existing content, it could be virtually anything.
What helps clarify it as such, is the fact that you've went out of your own way to provide a version of the product closer to the desires of the fans. A direct nod of appreciation, to show the bondage between you and the audience. Every remake of a game, every remastered version of it, despite being approved for profit reasons is also falling under the rule of servicing the fanbase.
A big example of that, are the Neon Genesis Evangelion (Shin - Seiki Evangerion) movies. Categorized as a fan service because they are created to satisfy the fans desire for a better (perhaps alternative is a better word) ending to the series. It's even stated on last addition to the saga, Evangelion 3.33, You Can (Not) Redo, that the movies have been partly if not entirely for the fan's satisfaction, as they will continue till the fourth movie gets released. The original television series first airing almost two decades ago (October, 1995), ended rather philosophically and abruptly.
The finale itself, mostly abstract in its nature (containing concept drawings, unfinished sequences, real-life stills and voice-over dialogue), has being heavily criticized by critics and fans alike, who considered even the possibility that the ending was forced from budget cuts. Thus, the creators have embarked on a quest to satisfy the thirst of the fanbase (cult, would be more appropriate) for a proper closure.
Fan service is a weird kind of love, nobody gets it, except the parties involved. Then again we could rule it down to explicit sexual content, but that's not what it's about. It's not logical, it's not even always good for business, it's the opposite of value-per-time-spent, but it's a wonderful thing we do, a silly anniversary to form a wonderful relationship.
