i go in and out of movie phases, too. it seems like when i do it it's more related to genres.
about a year ago i was on a WWII kick & watched everything i could get my hands on for months, then i saw the Tudors & spent a few weeks watching all 4 seasons

...then i had to watch Elizabeth & on and on!
the same goes for crime drama (SVU & First 48) & comedies (Dinner for Schmucks, etc.)
what i hate is when the industry goes through a "phase"....like a couple of weeks ago i wanted to go to the movies and there was seriously not one thing i wanted to see. sometimes between my dvds, dvr, netflix, library, vid store, red box i still can't find anything! then i just spend more time on YT!
