Was it "weak" to not have written some saber action scenes for the suited Vader?
It would have been nice for George Lucas to have written in a small suited Vader and Obiwan lightsaber confrontation in RotS? I hate to hypothesize, but after waiting nine years and three movies, and to have left the creation of suited Vader to the last 10 min of the film was a bit disappointing to a SW Original Trilogy Fan who has patiently waited for the "rise" of this character to see him breath and walk for two minutes screen time.
Recomendation Alert: It would have been nice for the Big L to have scripted in that Anakin was repaired right on a medical site, on the valcanic planet Mustafar! And, that in later scene when Obiwan opens a sliding door in another location, ala Empire Strikes back, the vision of a suited Vader! A quick lightsabert battle ensues between them leading a weak obiwan to escape "ala" a jump for your life like Luke in Empire. there you go, I didn't even charge the stingy Lucas, and I think WE ALL WOULD HAVE LOVED TO HAVE SEEN A SUITED VADER VS OBIWAN QUICKY SABER DUEL. ANYWAY YOU LOOK AT IT< LUCAS SHOULD HAVE TURNED ANAKIN A BIT EARLIAR IN RotS AND PUSHED IN A SUIT VADER VS OBI DUEL. "YOU KNOW THIS BE TRUE"(EpV, Empire)
