It's difficult to judge this movie because it's composed by three episodes.
Tognazzi's episode, "Sarò tutta per te", is good but not great, it has not aged well.
The episode "Si buana" is definitely funny, but a bit of a repetition of slapstick comedic ideas already seen in other films of Paolo Villaggio.
But Alberto Sordi's episode "Le vacanze intelligenti", is an absolute masterpiece of comedy which makes fun of the alleged sophistication of modern culture. It's fun and smart, acting is superb.
