Well,fans are hypocrites,they want new,original,shocking stuff,but then they want the original creature design too.If they get the original design as they pleased,they say the movie has too much homage in it.
I think that Ridley Scott has said plenty of times before that he cares about what he wants in his movies.
He said in an interview that the alien as a shape is worn out,not shocking,scary or original anymore.What does that say?
