Oh, I thought of another one. I don't know if it's been mentioned already, but before the big duel between Anakin and Obi-wan, they should show Anakin sensing Obi-wan's presence. Instead, he just sees Padmé's ship come in. Remember what Vader says to Tarkin in SW?

A tremor in the Force. The last time I felt it was in the presence of my old master.

I must say I think this was something I was looking forward to when the prequels were announced. I mean, it's possible he sensed Obi-wan, but during those scenes they show him more preoccupied with Padmé.
