I think the idea is that this is the opposite of new, that trailer screams “screw all this weird new stuff, we’re going back to the roots”. As for whether that’s interesting… eh, maybe? I’m not convinced a horror film can work when you already know what the monster looks like and how it works. Aliens is a fantastic sequel precisely because its makers recognized that the alien wouldn’t be scary a second time, so they changed genres and made it an action flick instead. The next logical step would clearly be a slapstick comedy. This doesn’t look like that, but who knows, maybe the trailer is deceptive. ;-)

It hasn’t even been released yet
