We just started watching Westworld on HBO and were pretty much immediately hooked. Of course, I was basically hooked after seeing the commercial last month, but the series is just fascinating.
While I never saw the movie of the same time, I'm thoroughly enjoying the series. The cast is spectacular, the storylines are mesmerizing, and it definitely gives you things to think about long after it's over.
Westworld is currently airing on HBO. Check it out if you get a chance.
