I decided to give it a shot. This is the longest list of anything I have compiled in years, so note this date.
I list a top 100 rather than a top 150. I noticed a certain bias for older movies at the top of my list; early favorites make a lasting impression, I guess. These are the ones I enjoyed the most, weighted mostly for overall quality but the 'cute boy' factor shows up often, as in my placement of 'Indian In The Cupboard' for example.
