The Fifth Element.
I had a TBI, and afterwards my memory kept resetting. Initially every couple of minutes.
The hospital told my girlfriend to just take me home and keep an eye on me, and I'd be alright in due course. Her and her boyfriend took turns babysitting me, and they just put the DVD of The Fifth Element on repeat because I knew all of it - it didn't matter when I reset, I just dropped into enjoying what was in front of me.
I remember the last reset, apparently 2 days after. It was like waking up, only I was already sat up in bed watching the movie, cuddled up with my family. I lost about 5 days of memory in total, but after a couple of months felt as sharp as I ever had :-)
Neither of them ever wanted to watch that film with me ever again, though.
