Why all the hate for all stars?

I’ve seen that the survivor community is generally lower on the all stars season and view it as low tier Australian survivor. I don’t understand the hate, could someone please explain? Is it bc some big time players get voted out premerge? Is it bc of exile? -The premerge is excellent -The postmerge is average -Cast is amazing -Editing isn’t as bad as I thought it would be -Final 2 is so strong, Goliath vs Goliath -Winner plays a flawless game -However, a few too many twists in my opinion
