The (bad and lack of) writing had a real impact on the chances for the actors to shine, though. Season 8 barely had any dialogue in it compared to other seasons.
Aside from episode 1-2, actors did a whole lot of staring with very short conversations. I'm struggling to remember any Alfie Allen dialogue at all.
I personally wouldn't have nominated Harrington(he's a mediocre actor imo) or Hedley(she was given nothing to work with). I have no problem with the rest. Clarke did a great job conveying emotion without saying a word. Plus, we all know what the deal is with huge shows getting nominations in their final year. Most don't deserve them. Popularity has been a factor forever. Voter fatigue is also a very real thing with the Emmy's.
