Vaderios, I believe that particular shot is from the AOTC deleted where Obi-Wan has Jango Fett's dart analysed by analysis droids. It was the first special effects scene finished but also the first scene to get cut :P

I agree with Ithilgore, the special efffects of TPM have aged the best. There are some really awful effects in AOTC, but I think part of that is because the shot the film digitally. Everything in AOTC looks too clean and fake. Seems they had that all worked out in ROTS, I think ROTS has great effects. The only thing I think looks truly bad is the Obi-Wan vs Grievous duel. The composition is bad, but the inconsistant backgrounds make it even worse.

It agree that it holds up, and most likely because it was shot on film... the grain, the softer picture... It tends to give it a more organic look. But there is no way that this couldn't be simulated in a fan edit. That's really the easy part IMHO.
