Unfortunately they don't really have any power, they got to do what the directors or studio wants, ADI are talented, they just need to work for someone who doesn't make them do designs that are disliked, Resurrection designs are good when looked at on its own and with the context that they are hybrids, not true Xenomorphs, but these designs are wrong for "pure" Xenomorphs hence the dislike of them in AVP.
I have no issue with them working on Alien V, hopefully they will deliver the bio-mechanical giger design.
