The premise is interesting, but so far I'm not entirely convinced by the series. There's arguably too much going on at the same time, with everyone having their own agenda. I just hope it doesn't end up like Lost.
Especially in that latest episode, I feel like we lost track of the character of Dolores. At times she appear to be controlled by something or someone else (Arnold?), to the point where she's now even misleading Ford, even in analysis mode.
I've actually seen the original movie a long time ago. While I don't remember the details, the story was much more straightforward. The hosts got out of control and started killing the guests, and it resulted in a chase between of the hosts and the main character, somewhat reminiscent of Terminator. It was an innovating movie in its own right.
