I think Lucas dropped a HUGE ball with the last shot of ROTS by having it be the Lars and baby Luke looking oout of the twin suns. Sure, it's a bit nostalgic for those who know ANH (and the Luke shot) intimately, but it actually doesn't make sense at all in the narrative. Instead, it should have been Obi-Wan looking out into the Tatooine distance after dropping off the "new hope" to the Lars. And why would Owen be looking out at the sunset and the future ala Luke anyway? He's not a dreamer... he's a grumpy pragmatist!
Plus, Obi-Wan is one of the key figures of the PT and is the major foil in getting things started for Luke in ANH. A closing shot with him would have been the perfect bridge between not only the 2 movies, but the trilogies. And for those watching the saga chronologically, exactly why are they supposed to feel anything for the Lars and newborn Luke?
Huge missed opportunity, imho. But just one of many, sadly.
