Like with any property, there are people who are excited and others that aren't.
I'm excited, why? Because there is nothing, absolutely nothing that suggests that this isn't going to be great, we have a passionate, kick-ass writer/director behind it that even starred in the original movie and a studio that is putting effort and money behind this and really hiring talent. What else should one ask for?
This is a great start for any movie and people should f**king be excited, considering where we were 10 years ago with the franchise, i'm damn grateful for this.
Same with Alien.
