critical understanding failure
Oh come on he got his lightsaber in movie IV and Obi Wan instructed him a little. Maybe he was not a full Jedi Knight or even padawan level, but at least he started going down that path.
Anyway especially Return of the Jedi is false to its name. It's not the return of the Jedi it's just the fall of the Empire. The only "Jedi" alive is Luke.
I guess the fact I saw the prequel before the originals also plays a part though. The original trilogy was in the theatre before I was born, and I watched the prequels first. I guess that makes me a bit biased, but it's still stunning how Luke and Han hog all the action. In the prequels sure Qui Gon, Obi-Wan and Anakin hogged a lot of the action but the other Jedi fought along as well, even more infamous Jedi such as Kit Fisto.
