There was nothing that blew me away like the above mentioned movie or "Boyhood" of "Mad Max: Fury Road". If you put a gun to my head I would say my favoritest movie of the year was "Sing Street" with "The Eagle Huntress" a close second but all of these movies (listed alphabetically) kept me awake for their entire run and left a lasting impression on me. Check them out.
