The friendly conversation between Obi-Wan and Anakin in episode three after they land the ship on Coruscant. For that scene, everything works, the acting, the dialogue, even a little of bit of the direction. Its one of the few scenes that actually feels like a real conversation between two genuine and likable people. Its actually one of the few times any of the films feels like it has room to breath rather than getting the plot moving or continuing the ham fisted character arcs. Had we gotten more of this between the two, I probably would have enjoyed the films more.

I agree with this. I always loved that scene. It felt like it was plucked from a better movie.

Also the opening scene of ROTS. Before people start talking.
