I think that Prometheus has the same plot as Alien vs Predator (expeditioners go to a remote place in search of something new, with a second in command who is female, and then they find themsleves in trouble, people die, at the very end a new type of Alien is introduced) but is done infinitely better.
In AVP the characters all have jobs which they do before being overwhelmed by experiences beyond their experience.
In Prometheus every character is an arsehole only the droid is following his programing.
As I say it looks good.
And yes Aliens is tatty (wrong aspect ratio, ugly titles, variable model effects, recycled score from other Horner movies, lousy rear projection) and lazy.
It’s by the numbers. Almost every lever of the plot either comes from the first film where it made sense (decompressing the Narcissus made sense because it was a small ship and Ripley is wearing a space suit, doing the same thing with the Sulaco would tear the ship to pieces and kill everyone in the landing bay) or it’s painfully cliche… Screaming child in peril…(yawn) look at how the Feral Kid turned that old chestnut on it’s head. Making Bishop a good droid deserves praise though.
