There really does seem to be this weird trend where, over a long enough period of time, every beloved franchise eventually gets completely taken over by people who despise the material and its fans. Lord of the Rings, Star Wars, Final Fantasy, Mass Effect, Doom... Remember all the promo materials for Dragon Age 2? DA: O was a runaway success that put Bioware back on the map as an RPG-maker, then all their marketing talked about discarding the stuffy overhead perspective and boring RPG mechanics in favor of a bunch of hybrid action trash that nobody asked for or liked.
Maybe it's just inevitable that creators get bored, but in a lot of cases the original creators are no longer involved and these decisions seem to be made by people who have no connection to the original work, which makes me wonder how they got the job in the first place if they so obviously hate everything that made the franchise famous in the first place.
