I can't speak for others, but as an avid 16mm collector, I like everything that is part of the hobby: tinkering with the projector, threading it, focusing it, experimenting( with different lenses, projectors, bulbs)
making repairs to the films, splicing film together, and of course all the joys of watching films the way they were intended to be watched, complete with the whirr of the projector, jumpskips in the film and occasional lines and scratches in the print. You can actually get the feel that these films date back to the 1930's and 40's, unlike DVD's which are so clean and enhanced that they look like they could have been filmed last week.
And guess what....even with the jumps, skips and imperfections, the Stooges are just as funny as on the antiseptic DVD's.
