The story follows a sort of theatrical structure: the setting is the same throughout the whole film, apart from a couple of scenes which took place in a nearby location. There isn't much action and everything happens during one single day: a group of old friends meet up at the beautiful sea house of a couple of them and they get lost in their existential conversations, doomed by a comet which is about to hit the planet. The characters seem on stage, wandering about and getting lost in their deeply melancholic conversations.
I expected much more from this film, considering some of the names starring (for instance Alessandro Gassman, Edoardo Leo, Valentina Cervi...) and the great director, Liliana Cavani. What I enjoyed was simply the beauty of the landscape, a few funny lines and the special effects when the comet approached.
The rest of it was disappointing, most of the protagonists were disappointing and their human relationships were the most disappointing aspect of all.
