For all intents and purposes, there is an actual zombie apocalypse going on in Hollywood. It has been going on for a few years now. Long dead film franchises are constantly rising from the grave as rotten and horrific husks of their former selves. It is this tendency of re-using ideas that Merfish pokes fun at in his most recent GTA V fan video. Merfish has built up quite the reputation for himself in the Rockstar Editor community with his over-the-top, crude and satirical parody remakes of TV intro sequences and big-budget movie trailers.
The Merfish flavor of humor is the one where excessive violence, uncalled-for turds and dildos are featured prominently. It may not be everyone's preferred flavor, but Merfish pulls it off in such a way that it just hasn't gotten old. His videos are extremely popular, with reason. Personal opinions on his sense of humor aside, the videos are extremely well made and put together. There is ample evidence of considerable attention put into the details.
Some time ago a reboot of the legendary and well loved Ghostbusters franchise was announced, with a few changes to the tried and true formula of the older films. The new take wouldn't re-tell the same stories with a new coat of paint, but continue on from the originals with a new cast of characters.
