What do you think of it?
PEN-si — stress on first syllable. The 'e' is open, like in 'pen'.
Ask a friend for their opinion immediately after the film. One of the most versatile and common Italian conversation starters. Can be used for any film, book, restaurant, or experience.
'Che ne pensi?' contains the particle 'ne' which refers back to what was just experienced — the film, in this context. It cannot be directly translated word for word. The equivalent direct question 'Cosa pensi del film?' is slightly more explicit but both are widely used.
Com'era secondo te?
How was it in your opinion?
'Secondo te' (according to you) is a key phrase for soliciting opinions.
Ti è piaciuto?
Did you like it?
Simple yes/no question about enjoyment.
Cosa ti ha colpito di più?
What struck you most?
Deeper question — invites more analytical response.
Post-film discussion is a serious Italian social ritual. It is perfectly normal to spend as long discussing the film as watching it — often over a coffee or an aperitivo at a nearby bar.
