Hobbit and Redhead says:

The places look great!

My only beef — it is painfully obvi­ous in these shots that the same mobs are reused as we encoun­tered in Angmar and else­where. There is some logic in this (Sauron has a lim­ited stock of min­ion tem­plates to work with), but see­ing a new mob type is so excit­ing (psy­che­delic frogs in the Water­works), I can’t help being a lit­tle disappointed.

But it could be just these screen­shots, and Tur­bine is sav­ing the best for release to have the great­est impact. I am an eter­nal opti­mist, after all.
