I thought the trailer was really good. Thought Bendict Cumberbatch did a good job with the narration.
I know that a lot of hard core Star Wars fans felt that the franchise would be ruined by Disney buying Lucasfilms and the exodus of George Lucas, but J.J. Abrams is a really good director. I liked what he has done with Star Trek. He also did a good job with last two Mission Impossible movies and has several hit TV shows including Felicity, Alias, Lost, and Fringe.
I guess only time will tell.
So, do you think Cumberbatch or Gary Oldman is going to play the Sith. It is rumored that they have both been hired and it is also rumored that they were originally considered for the same part.
