That's because, unfortunately, you didnt get to see their relationship between AOTC and ROTS. That wasn't covered more closely until he started doing the Clone Wars animated show. However, it's clear that they're much closer to each other in the first part of ROTS before Anakin starts turning. The only parts of ROTS that I disliked was the early scene on Padme's balcony, a couple of the small scenes between Anakin and Palpatine(but not the opera scene. That was cool) and that's about it. Everything else pretty good to great, IMO of coarse. I really enjoyed DH2. It's my second favorite HP movie. The only thing I didn't really like was the way the deaths of Tonks, Lupin and Fred were handled. That was bad.
