Super late to checking out the nominations, but for as weak of a year as '08 is, I feel the nominations definitely hit just about all the marks for the year.
I honestly feel that '08 is a very strong year, and the nods are pretty much on point. A shame that some of the smaller films didn't make a splash (poor Redbelt and Lorna's Silence), but what can ya do. At least the dreadful Oscar BP lineup got shut out of our own.
That adapted screenplay lineup is painful, though. Although I can't think of much to replace it -- all the best screenplays were original. And all the halfway decent ones, for that matter.
That's fair. To be honest, quite a few of my favorite films from that decade are from that year (WALL-E, In Bruges, TDK, just out of what was nominated), but it's a very top-heavy year which is why I consider it a weaker one. After about the #20 mark on my films list that year, the quality starts to drop significantly. Then again, I'm sure there are always some great hidden gems lurking somewhere for me to see at some point that could change my mind (not even seen Lorna's Silence that you mention so there's one already).
Agreed on screenplay though. My winner is Let the Right One In for adapted, and even then it's not a screenplay I'm in love with.
