This trailer is certainly MUCH better than the 1st one they released. Although it does look good, I admit, I am hesitant. The last three Star Wars movies were like a wet match. It tried, maybe a spark here and there; but, it never caught fire. Ultimately, it was disappointing. Also, why not release in May like the others? I assume is that Christmas time is a bigger movie attendance window, and by announcing now, it generates interest, and also, in a way, warns other movie studios to not even try to release a movie in that time frame, as they would surely not compete.
As for me, I actually may wait. Disney has had some blockbusters (Pirates of the Caribbean) and epic flops (Lone Ranger, John Carter). The flops were very unfortunate. John Carter was not marketed correctly, so fans, who did not read the books had no idea how he was. The Lone Ranger was a complete mess, as it seemed to me that they tried to go in a different direction, and ignored the serials, tv shows, and prior movies with Moore and Silverheels.
I think I may wait this one and see how others react first, then decide if it is worth seeing. Crazy I understand; but, given movie prices are getting expensive now, combined with all the extras (concessions), I do not wish to be disappointed.
