There are a lot of reasons to not judge it yet. First and foremost, the director/show runner has zero input on the trailer. That’s all the marketing department, and the trailer is designed to get as many eyeballs as possible on the final product. Numerous examples exist of trailers which bared little resemblance to the movie/show/game/whatever.

Secondly, they buried the lead on the director. Jonathan Nolan did direct much of Westworld. But he also wrote a bunch of award winning films for his brother, Christopher Nolan. Movies like Memento, Interstellar, The Prestige, and Dark Knight. He’s no slouch, and I’ll reserve judgement until I see it.
