Several years back I realized that I had trouble diferentiating between the movies I liked and the movies I loved from the early part of the year. Roger Ebert has always suggested that this was true of the Academy and why the Oscars have such "short attention span." He recommended a midyear ballot to go along with the end-of-the-year ballot combining both to create the nominations list.
For me, I decided a mid-year top 5 usually works. I wait until July 15, since the first few weeks of January are generally a wash for new releases, and so 7/15 is a little closer to the mid-point. This year, although I had many "nominees" for the top 5, I found it tough to pick a top 5 (sorry, although it would have been "eligible" I haven't yet seen Harry Potter).
I have thirteen "nominees" for my top 5 this year— just two at the top, i.e. "must see" (Dogtooth and Midnight in Paris). This years nominees (films I'd seen by 7/15 that made my "must see" and "recommended" categories) include: The Adjustment Bureau, Bridesmaids, Cedar Rapids, Dogtooth, The Hangover Part II, Just Go With It, Limitless, The Lincoln Lawyer, Midnight in Paris, Paul, Thor, Water for Elephants, and X-Man: First Class.
