It's pretty much been established what the force allows one to do. Astral projection and peeping in on people is not among them. Eight movies and all of a sudden these nonsensical powers are pulled out of some idiot writer's ass? I'm actually physically disgusted at the stupidity these pathetically incompetent and juvenile writers portayed.
Luke seeing and hearing Obi Wan is not even close to the same thing.
Blame RJ , the man that dared to be different and gave us some Indie crap desperatly trying to be the new george lucas
shareIt's fine to be different, if you're talented. That wasn't the case here, and that's where the blame lies. What's more bothersome is the fact this script won best screenplay at the Saturn Awards. Whatever those are. Clearly someone made a giant donation to buy the award in the hopes of mitigating this tragic failure. Sadly, it was simply another failure.
shareTo be fair, Rian didn't invent that: http://starwars.wikia.com/wiki/Dopplegänger
It first appeared in Dark Empire in the early 90's.
I don't like Rian, but he was using pre-established lore.
