Greetings from Lithuania.
"Don't judge a book by its cover" says the old saying. This saying could also be perfectly used for TV shows and by saying cover i do refer to pilots. Pilots are always made with all possible resources, money and etc. to attract the viewer, so usually pilots are amazing. But you can get an overall idea of the show like after watching 2 or 3 episodes.
Same is here with the new high profile TV show "Westworld" (2016-). Opening episode (aka. pilot) was really great, 10/10 in my opinion. Second episode was a bit weaker, but still a very good chapter. Acting by a GREAT cast in "Westworld" is uniformly good, but nothing that specially good for which anyone in here so far could get some big awards. Production values are amazing, clearly a loot of money were spent on this show (although it's not quite "Game of Thrones" also).
Overall, so far a very intriguing plot, amazing production values, great cast doing its uniformly good job will get me to the screen for next episodes. Just hope they won't make "Westworld" into another "Lost" during its run (as much as i loved the first season of that one, they ruined the series later). Great show so far.
