Well, the word "boring" isn't actually used, pdq, but I think Little Hawk got the sense across fairly unambiguously:

"I have wondered for years how audiences could put up with those interminable Jimmy Stewart movies where people talk and talk and talk and talk....and very little else ever happens. After all, even listening to Jimmy Stewart ramble on for a mere five minutes or so could easily drive me to considering death by gerbil inhalation."
