I've seen a couple over the years: Robin Hood, Twelve Chairs, Blazing Saddles, and most recently Spaceballs. I found them all funny, theoretically, but they rarely got an open laugh out of me. It seems like most of the time this is just because the comedic timing makes every joke or funny bit land very awkwardly, or with just a bit too much space to leave room for any subtlety or reward for the watcher.
I feel like I remember the few I saw as a kid being funnier at that time. Is it just because my brain has been attention-poisoned with the rapid fire wit of modern comedic television?
Absolutely, but my point was a bit more specifically about timing. Something about the comedic pacing just felt like it kept jerking forward and then hitting the breaks.
