Honestly, where can they go with Prom 2? It'll probably turn out hokey Star-Trek-esque no matter what. I like the whole weaponized Alien concept going on in the first film, but I feel it was something that just wasn't focused on enough and it wasn't scary or suspenseful. The idea is there but it's not properly realized.
We need that dark, unknown, Giger, hellish universe presented in the first Alien film to come back.
