Yeah i felt Vaders pose and costume was a bit off. He's ok in the combat scenes but his movement is a little too fluid and the helmet/neck section with the cape looked off. I was sure vader had a chain connecting his cloak.
But minor gribble.. certainly didnt have the presence Prouse had.
I also heard Bail say 'trust HER with his life'. Now they could be referring to Leia but they also say 'your friend the jedi'. By this point no one knows Leia is force sensitive, not ever her, and she is not a 'jedi' because she, like Luke at this point is unaware of their existance and has had no training.
The prequels and everything Yoda said in the OT have led us to believe that you are not 'born' a jedi, you can have potential but it takes years of training and that not everyone succeeds.
So its either a massive dialogue fail and fails because
1. they mean Obi Wan and put the wrong pronoun in .
or
2. they mean Leia and use the wrong job title
or
3. Its a cut section where an actual female jedi was shown or referred to and we dont see it.
I think I heard 'general syndalla' (sp) and again, like others have said the 'rank' system in star wars is ludicrous given generals usually end up in command of ten man strike teams, commanders have four man ships etc etc but 'corporal calrissian' doesnt have that 'power' does it.
