I remember watching 'The Neverending Story' for the first time. I hadn't seen it before and was alone, and it was on TV, so whatever.
I actually found it boring, and wandered out of the room a few times--typically during commercials. Another couple of times it was a large-ish chunk.
What I'm pretty sure happened was that they were playing the movies back-to-back, all of them, in a marathon. So occasionally I would come back and the plot would be slightly different, but the same characters, and suddenly the action was building yet nothing from the previous plot had been resolved.
...this went on for 7 hours. Approximately.
Until much, much later I was convinced it really WAS a Neverending Story and I'm still a little scared to rewatch any of the movies in fear that I'll be trapped watching it forever.
Aaaand I'm pretty sure here's where I admit I had no point to this.
