So first i watched it in the cinema and i've never seen a movie from the Alien franschise before, and after the movie ended as felt abit "meh, special effects nothing more" Then a friend told me i at least should watch the 2 first Alien movies and so i did and now i re watched Prometheus and it is SOO much better if you've seen at least the 2 first ones. It comes of as a new franchise but to be honest, a lot of the things explained and seen in Prometheus were something you wondered about from the 2 first films.
So in the end, watch at least the 2 first ones (both really good, the others are not so) before you watch Prometheus
