I really wish it would’ve been done that way. Anakin should be critical of the Jedi. It would’ve been great if Anakin would’ve tried to bring Obi Wan over to the dark side, and when he saw his friend and master wouldn’t leave them, the duel begins. It shouldn’t have been a “I murder children now”. I never got that vibe from Vader in the original trilogy. He felt dignified, even if he was a “bad guy”. Instead, AOTC and ROTS both paint their relationship as rocky. I never once felt like I was watching friends. Hell, Luke and Han don’t share that much screen time together, in all 3 films together…but we know they are friends. We get that vibe from them. Obi Wan and Anakin, not so much.
