Alien related or not....it will be defenately better than avp.....avp movies were not scary.
Had no depth and the second one reminded me movies like: ''i know what you did last summer'',''final destination'' ect....
Even alien 4 was 300 times more serious,scary and solid movie than the 2 avp movies.
I dont like Ridley changed his mind about the alien prequel or whatever this is going to be...but
He would never do a movie of that style and depth.
