I am still baffled how they managed to rehash literally everything from JP in JW, yet couldn't bring any characters back (not counting Wu). Made worse by Trevorrow's and other people's excuses of it not being appropriate, needed or possible. Really, but everything else you did was? Sure, we all know scripts cannot be modified.
Anyway, I don't think Neill particularly cares at this point in any case. Goldblum sort of seems to, but not to the point where he would go contacting them specifically.
