As someone whose first exposure to the old Bond movies was on TBS' annual holiday marathon weekends that was a major nostalgia hit for me. Sure, I own them all on DVD or blu ray and could put them in at any time but it just hits different when I can turn on the TV and it's in the middle of The Spy Who Loved Me just decide to let it roll. (Also, they stretch them out to like 3 hours with commercials which also brings back memories). I don't need it to always exist, but if they want to pop it back up on holiday weeks/weekends I'm probably going to throw it on.
