Is this one of those "In my kid mind it was cooler" posts?
Because you certainly didn't answer my question. How is that a legacy?
He had less than 10 minutes of screentime, yet people seemed to love him quite a bit, so they brought him back and had him do a bunch of bounter hunter shit that was pretty cool. Unfortunately they went overdose with the Prequels and then cut the rest of his legacy out.
Have you read any of the books or comics? Tales, Adventures, the Omnibus stuff...He did some really awesome things in those.
Unfortunately, either way, the EU has been mostly removed so I'm not sure what is cannon anymore. He got dusted in ROTJ and I guess that's that. The cool stuff was the comics and book that came out after the OT. The shitty stuff, however, emerged during the prequels, and mostly everything of him as a kid, the cloning crap, and the Jango prequel stuff all felt extremely forced to me, which is, I think, what we're stuck with.
I'm not saying you're wrong about his legacy. I'm just saying his legacy would have been better if the prequel stuff wasn't so in your face with his history.
Hope that makes sense.
