I don't understand why people think user reviews are a fine metric to see how good a show is. (As in ever)
So here's mine:
Visuals are amazing and approaching the LotR movies. Way better then the Hobbit.
Dwarves look awesome so far.
Short hair elves are weird at first glance but not a deal breaker. Probably their hair grows incredibly slow.
Pacing is off, like a lot.
Don't like Galadriel but can't tell you why.
So after two episodes I'd say 7/10
And the stranger has to be Sauron or Morgoth/Melkor.
Would be way too early for an Istari.
