The dialogs are a dream come true.
I heard some people were upset that Michelle Pfeiffer was cast as Frankie. Apparently the actress who played that character on stage was Kathy Bates and came to be regarded by many as definitive in that role. I'm sure she was terrific, and I loved her in "Dolores Claiborne", but as much as I sympathize with those who claim that it's all part of Hollywood's conspiracy to make ordinary women feel dissatisfied with their "real", ordinary bodies and faces, Michelle Pfeiffer - gorgeous as she is - is a sensitive, real performer, not a Barbie doll in any way, and though I couldn't be more different from her physically, I find it very easy to relate to her thanks to her talent.
The movie is a gem, though every time I watch anything with Al Pacino in it I'm always counting the seconds for the "scream scene". I'm not sure I ever watched a movie in which he starred, that he didn't scream his head off at some point, and this one's no exception. One love scene is basically spoiled by it, although die hard fans can always make the case that the script was asking for it. No minor problems like this one can spoil the movie as a whole though, that's what's important.
