The other side of this is: The items with overwhelming rough and nasty feedback by a large amount of passionate forum members are the ones that usually get addressed in a decisive way by Sideshow because the complaints and bad publicity are just too loud to ignore.
If people complained louder about Galadriel PF or Namor Comiquette with the same passion (backed with the amount of cancellations) we may have gotten better products for those. In other words, acting civilized will only get you so far with Sideshow. That's just how it is. It's like, if you don't like the Bruce Lee PF then that's tough. Don't like it, don't buy it.
I am all for constructive criticism. I think it makes for better discussion than snappy one liners, but then again, this is an internet forum so it's the nature of the beast.
