I've heard a lot of debate over the years about R2-D2 and C-3PO's roles in the prequels. Some are satisfied and some are disappointed in them. I'm the satisfied one. R2-D2 has the great type of heroic moments I always hoped for. I guess if I had to suggest a negative aspect of him compared to the OT, I'd have to say its his "personality". He doesn't get excited and hop around, nor does he reveal much emotion in his beeps and chirps (how silly does that statement sound? ). As for C-3PO, I've never been bothered by his crazy antics. Call me lame if you must, but I actually laughed during the Arena scene I guess the big question is, is this the way you envisioned the ultimate droid duo to be in the PT? Are their journies the same as you hoped? What do expect of them in ROTS? And of course the biggest question of them all: What were their wedding vows at the end of AOTC?
