Suppose I can throw at a few crumbs at this stage. lol
Drama Pic - 12 Years is not a 75-80% fav to win this, no idea why the odds are set the way they are. Go against it at roughly 3-1 and also put a small bet on Philomena (should be able to get over 30-1) for the upset.
Comedy Pic - AH very strong fav but probably wouldn't bother at -500 or whatever it is now.
Drama Actor - Again 12 Years isn't this strong and Ejoifor is too low. Redford or McConaughey are probably more likely, for betting purposes I'd put my dollars on the latter at +250 type odds for the win.
Drama Actress - Blanchett rightly large fav, nothing too interesting. Bullock and Dench within the realm of possibility but the odds are about right here.
Comedy Actor - Nothing too strong but I'd bet DiCaprio at current odds for a small bet (-130/-140 type odds).
Comedy Actress - Odds have come down so not as exciting but still put a small bet on Adams at around even money. Adams in the more popular movie and never won before, should be enough to push her past Streep.
Might add a couple more suggestions later.
