First of all what an acting performance from Edie Falco and James Gandolfini. Amazing dialogue between them amazing dynamic, heartbreaking and depressing. I think this episode has a big impact on Tony's character you can really see two different persons after season 4 and before this episode. In my opinion this is one of the most if not the most underrated episode in history and it's maybe also my favourite oat which I didn't expect after watching so much. A lot of people told me Season 4 is the worst season of the Sopranos it may is (it's still amazing) but this episode stands really out. In conclusion: perfect acting, perfect dynamic, perfect development and perfect writing.
