Absolutely.
I must say that watching the good LBT movies does make me somewhat sad, which may be one of the reasons why in fact I watch them only very rarely. However, I'm positive that if it wasn't for that kind of sadness (which struck down really hard when I "rediscovered" LBT in December 1998 and watched LBT 2 to 6 within a few weeks) I would not be an LBT fan. It is difficult to pinpoint all the causes of that sadness or the reasons why it seems to be so important. I'm generally an optimistic and happiness loving person, so it doesn't make much sense to be so taken with something that makes me sad to some degree. Then again somebody once said that melancholy is "the joy we derive from being sad". Maybe it is something along those lines, but that is certainly not the full explanation.
