Wallach was annoying, but Sofia's performance grated on my nerves like nails on a chalkboard. UGH! Add that to the ZERO chemistry she had with Garcia, who I actually liked in the film, and she pretty much ruined the film for me.
The confession scene with Lamberto is great. I loved almost all of the Sicily scenes, especially those with Kay. And although some here don't feel it was in Michael's character, I loved Michael's monologue at Don Tomassino's coffin. I've always felt that Michael was actually speaking to his father, since Tomassino was a father figure to him.
