OK, best dramatic presentation: let's do this thing.

...they really need to fix this category and if they want a category for TV drama series they need to have one, and go back to letting people nom entire series like they used to, instead of pretending it's "short form" and people are nominating episodes. Anyway.

Best Dramatic Presentation: Short Form

Two nominees:
Doctor Who: "Listen"
nope. sorry, but I noped out of new-DW ages ago and am not going back. give me Doctor/Master that's actually doctor/master and not Moffat's "definitely not gay also I have lady issues" thing and I might go back. maybe. but not for this. nope.

( Orphan Black )

Best Dramatic Presentation: Long Form
Two nominees

( Captain America: The Winter Soldier )

( Edge of Tomorrow, marketed on DVD as Live, Die, Repeat: The Edge of Tomorrow )

Bonus puppy-noms analysis for longform, since I know a lot of people were planning to ignore the puppies on this one, given that the studios don't care about the hugos anyway:

( Puppy noms, short discussions )

I would have happily voted for Big Hero Six above any of these.
