I can't pick a "favorite".. There are quite a few movies I'm fond of, and depending on my mood, nearly any one of them could be my "favorite" at that time...
It's kind of like asking me to pick a favorite Madonna song. One day it could be "Borderline", the next it could be "Material Girl"... Or "Ray Of Light".. Or the live version of "I Love New York"...
However, I can say with nearly 100% certainty that my least favorite movie of all-time is likely to come out next year, and be another darned remake with a horrible cast, and desecrate one of my fondest childhood memories, and...
Ohh, I'll spare everyone the obscenity-filled rant on why having anyone besides Lynda Carter play THAT role is as sacrilegous as believing anyone but DeForest Kelley could play Bones McCoy...
Let's just say Maddy isn't likely to be very amused.
But, going back to a favorite? I don't know.. Before I've been on my recent kick of watching classic TV shows that didn't make it to a fourth season, the last movie I watched regularly was Happy Gilmore.. Of course, I'm more amused over a particular scene in that movie than anything else.
