Like in the old days.

Having not fande too much the last two episodes, is caught up with "The screaming fog" again. Stark on "Nebelberg" and "terror from the Moor" remembering. It is working with well-known elements of previous episodes; and for that very reason I find this episode so scary succeeded.
The humor may be a little hidden, in return there this time duly much tension.
For fans definitely a must if they do not fix their expectations too high.
