"Obi-Wan is weak" isn't a valid criticism
Some of you have no depth or understanding of how stories are told. Ob-Wan didn;t just beat Anakin, he mutilated him. He left him with little more than a torso and 100% was left was melted into mush.
He then disappeared, stopped using the Force, and then finds out he's not only alive, but a terminator that has been doing the Empire's dirty work for 10 years; all while he's stopped using his abilities. Go take karate, BJJ, or hell even just lift weights frequently Dedicate years to it then stop for a decade. You'll be terrified and gasping for air if you get into a situation you have to defend yourself. His current situation makes complete and total sense.
Not to mention, Jedi's abilities going in and out - as their confidence wanes - is WELL-ESTABLISHED in this franchise.
Absolute morons making this argument.
