What makes a movie good? And why do we re-watch them?

     The things that make movies "good" and interesting are mainly Plot, Story line, and Overall Content. The main reason I would watch a movie again is, because I loved that specific movie at that time and the memory of the feeling then drives me to watch it again even if I wouldn't normally be in the mood for that type of movie. I will always re-watch movies that I liked in the past, but I will subconsciously avoid any movies I didn't like for any reason. Movies are also just a very stimulating part of my life and they keep me awake when I need to work and they put me to sleep when I wish to sleep but just can't.
