Every single resort has had people who love it and people who don't like it at all and the rest somewhere between and many posted their thoughts about them on multiple threads and even the same thread more than once. I don't see a lot of difference in that regard.
DVC drew a line in the sand with the resale restrictions which adds a negative in many owners minds that came about with Riviera but that doesn't have anything to do specifically with things about the resort. It would be the same reaction if it had happened with CCV, PVB, VGF etc.
I'll take a stab at the top negatives of most resorts from the past 12-15 years that in the past that were covered repeatedly and still are today:
SSR - too big. Looks like Grandmas house - bland decor. Points too high - should have been the same as OKW. Remote and buses only.
AKV - too far from everything. Buses only. Too dark. Animals are going to increase dues a lot.
BLT - cheap "Ikea" furniture. Overlooks a parking lot. Tiny studio with bathroom sink in the kitchen. Small pool.
Point charts too high..
VGF - looks like Grandma's house. No great views was a big one before it opened. Point charts.
PVB - studios only and too dark. Oh - Bungalows. Destroyed the Poly resort. Point charts. Dues.
CCV - Occupancy, dues, too many Cabins. Decor had a fair amount of discussion.
Riv - overlooks a moderate, Skyway, decor, point charts.
Decor, transportation, dues, point charts, amenities, views. All a commonality.
I've probably missed a few but most of them still come up pretty frequently. These specific boards discuss DVC and DVC is a collection of timeshare resorts that are not identical.
