Roger Davis usually seems just average for a DS actor to me, not great, not bad. In storylines where he's annoying, well, I find the others annoying too. Some storylines I don't like. In the "present", he seems to be "just a guy", interchangeable with dozens of other "just guys" who came and went. In the past he's better. Bradford's fine, his loyalty is touching (straight line there)... I've seen the end of Dirk and then Tate, and some good moments there. Who wouldn't get angry being controlled by Petofi? He really likes playing crazy people, and I like watching it. Centegenarian Tate in 1970 is a scream.... pay no attention, my head falls off all the time!
