New era Who? My fav's seemed to be either two episode or one episode. RT Davies? Blink, Family of Blood, Human Condition, Silence in the Library - Forest of the Dead (?), for example. The arcs never really worked for me that much - I'm not sure Doctor Who works well with an arc, Torchwood did, but not Who. I don't really know why - it may be the model of the two travelers having varied adventures that's the reason? The Impossible Astronaught, and Let's Kill Hitler kind of worked really well as stand alones?
