I think most of the dislike towards the game comes from the fact that no one asked for it in the first place.
People didnt even exspect a metroid game on 3ds.
And the whole "people complaining about change" aspect in the fanbase already started when prime was released
Also,i have to give ff that,it makes more sense than Prime Ball
The only time the fanbase was right about a game being crap was when Hunters was released (imo)
That game really was a huge dissapointment,ff atleast feels like a Metroid game
