The lack/snub? of names and films this year is mindnumbingly confusing. I mean, The Book Thief gets one nom, original score (John Williams)? Michael B. Jordan gets nada? I guess this IS the most subjective industry.
And I haven't seen Nebraska, so I can't comment on Bruce Dern's performance, but I've heard some terrible things about that movie. The noms kinda shocked me.
If you're familiar with the theory of primacy and recency, it's simple. EVERY nomination but a tiny few were from films released after mid-November. Kinda sad and lazy on the part of Academy voters.
