Probably Guardians of the Galaxy or Dawn of the Planet of the Apes. Both were phenomenal. Especially Dawn which I found to be groundbreaking, and showed that an action movie can still have real brains and genuine drama while still being engaging.
To be honest I haven’t actually seen that many films from this year. I’ve still got to see Frank, The Zero Theorem, The Raid 2, The Grand Budapest Hotel, Set Fire to the Stars, Foxcatcher, Get on Up, Calvary, Lost River, I Origins, Dear White People, Macbeth, and Mommy.
I’m a bit pants at seeing new films.
