I've just made my nominations. Nothing in particular I want to recommend in most categories, but I do have two for best short dramatic presentation that may not immediately come to mind:

For 2015

Person Of Interest 4.11 - "If, Then, Else" - the lovely one with The Machine trying to solve an insoluble problem and keep all of the human protagonists unharmed, and nearly succeeding.

For 1941

Dumbo - it's too short to get the long form award, but I think it's eminently worthy of consideration.

later - except that things nominated for 1941 have to originate in 1940 - Dumbo is out, Fantasia is in.
