Mmm. A difficult question...
I'm not very interested in cinema and I don't understand nothing about films and its quality or making, but one of my favourites is "Catch me if you can". DiCaprio and Tom Hanks play their characters perfectly. I like the history of Frank Abagnale Jr. and the "age" of the film and the music.
I don't care whether it's a drama film, or a comedy or a romantic one, I just only need to like the history, and if I like the music too, I "get in love" with the film :)
