I'm with you in retro-hating LOST, but I don't think this is that. I think they will have viable real-world (so to speak) explanations for everything. They have already started showing that and some of the ideas are very inventive IMO.
LOST was just completely ridiculous busy-work.
I'm not sure what Abrams role is but Jonathan Nolan is much more front-and-center in the creation. Writing and directing. I am feeling more of the Nolan fingerprint on Westworld. A little over-engineered at times but always with a direction and an underlying intelligence.
