Still haven't seen any of those (minus Chronicle - which I also enjoyed).
Right now I'd have:
Life of Pi
(Still haven't seen Argo, Lincoln, Silver Lining's Playbook, Zero Dark Thirty along with the ones that you mentioned)
Pitch Perfect takes best comedy as well.
Definitely gotta see Django and End of Watch, and Beasts is definitely a hate or love sort of movie, so I'd recommend reading up on it to see if you wanna check it out.
I plan on watching Moonrise, Pi, Paranorman, and Pitch Perfect at some point, along with like 10 other 2012 movies haha.
