Entertainment vs Art
Many will state a film is purely for entertainment and many will argue for the artistic values of a film.
For me 8½ has little entertainment value, however artistically this film excells, not so much in the story or ideas but in the camerawork and cinematography. I personally respect the value of art in a film but it needs a core substance to entertain.
To conclude I found 8½ a dull affair which I did not enjoy. That's not to say I don't like Fellini as I thought Nights of Caribia was great.
