2. Back To Basics
I've made mention of this a little already but it needed it's own entry so I could abbreviate on it some. Ridley Scott's Alien featured none of the over-blown, over-exaggerated action set pieces that its predecessors relied far too heavily on. Scott will bring the series back where it belongs by making it as terrifying as it used to be and reintroducing the Xenomorph as a monster to be feared and not easily killed. The monster doesn't work if the characters can blow up dozens of them with ease like in Aliens. It ceases to be frightening if it takes a horde of them to kill one person whereas in Alien the beast was so horrific because of the approach that Ridley Scott went with. He decided to keep it hidden in shadows for most of the movie which amplified the scares when it did appear. The less is more approach is really what Alien needs and Scott knows how to deliver that.
