Ive got a few but in no particular order.
These are just to me persoanlly so please don't wish me dead because I'm just answering the question. These are my answers just now but could always change in the future.
-Predator concrete jungle was a great game and should have been established as canon at least to the AvP universe.
-Paul Andersons AvP movie was actually a good movie.
-The Predator 2018 wasn't as bad as people made it out to be and if it is its because of other reasons besides bad cgi and the pacing.
-The events of Predator forever midnight should not exist nor the book itself.
-The Alpha Predator back story sucks and makes the yautja or Hish look more like dumb animals.
-Not every Predator fan wants the next movie to be set in the past but instead either present time or the not too distant future with a completely different plot than the one currently provided online.
-Predator Stalking Shadows is actually an entertaining novel with great back story and follow up to the previous predator movies.
-Predator Hunting Grounds doesn't actually provide any input or lore to the predator universe and shouldn't ever be considered as canon except for the recorded tapes by Shawn Keyes and Dutch as references to the novel.
