Few things can be as exhausting as a film festival.
From early in the morning to late at night you get to see movies, movies and more movies. Sounds like paradise, but it isn't. Take the Toronto Film festival for example, three hundred and seventeen films over a period of ten days. It's impossible to see everything, that would mean seeing thirty features a day, but even seeing a tiny fraction requires a heroic amount of zitsflisch. Five films a day can turn the mind to mush.
