In my more than 40 years of watching movies, only one time I left the cinema, I think I was 16 and a fan of sci fi books, in particular a fan of Arthur C. Clarke, so I went to watch "2001" and I left within 15 minutes! I tried again the next week and the movie is one of my favourite movies, every time they show it on TV I need to be careful to skip the channel, otherwise I get hypnotized and watched it again. On a side note, my dog "ate" my blue ray copy of it the first day we brought him home, not a good start for him!

So, I think sometimes you are just not in the mood!
