Yep, Vader looks great and makes everything in Star Wars better as far as i'm concerned...especially in Rogue One. That movie jumped from a 6 out of 10 to an 8 just by adding that Vader scene which was phenomenal. The bigger issue to me would be(i'm sure someone has already said it by now) transitioning from Ewen to Alec. In the trailer it shows Kenobi looking at a 5yr old Luke(I think). I'm not convinced they didn't merge those 2 viewpoints with a different scene because to me, he should look a lot older...or Alec looked old for his supposed age. Yes, i know ...13yrs in the Tatooinne desert, stress, yadda yadda. By the way, this is not a problem for me per se but just in comparison to Vader, seems to be more problematic, if at all.
