The SH fanbase like to bitch about every game that came out after 3.
Funnily enough, it becomes incredibly obvious that 50-75% of these people have never actually played any of those games when asked why they're so terrible. The resulting complaints can basically be summed up as "we want games that are exactly like 1, 2, and 3".
Personally, while I don't particularly care for Origins and Homecoming, I love how the series doesn't really play it safe like so many other game franchises, and is willing to try out different thing.
If anypony's skeptical of 4 (thankfully, though, the general reception for this has been getting more positive recently), Origins, Homecoming, Shattered Memories (which is a reimagining of the first game that runs in a different direction, and not a remake), and Downpour, I'd recommend playing them for yourselves (used copies aren't too expensive), form your own opinions, and ignore the fanbase.
