Huge Plum fan here!!! I have not seen the movie yet.
I was not thrilled with KH, but in the previews, she seems to pull off Steph pretty well. I know some fans are upset with the casting of Morelli, but I think he was cast pretty well. It is kind of how I pictured him in my mind even though JE describes him as tall, dark, Italian and with longer curly hair.
I think Connie is dead on (again only from the previews I saw.) Not thrilled with Debbie Reynolds as GM, I think she is fabulous, just not what I pictured as Grandma Mazur. I really think Estelle Getty would have been perfect, obviously not possible, but her character in Golden Girls is totally what I picture as Grandma Mazur.
I was disapointed in the casting of Ranger. I think the actor is really handsome and I am sure he is a talented actor, just not Ranger. In the books, he is described as being the ultimate bada** tall, mysterious, built, buff, muscular etc. In the previews, it shows Steph and him at a gun range, and Steph towers over him. He seems too "pretty" to be Ranger. I guess I'll have to see the movie to see if he pulls it off.
Keep the reviews coming!
