I think the reason people are reacting to Harrison in the trailer the way they are is because people have been wanting a film with the original cast again for many years. If you remember back in 1997-98 when they announced the prequels, people still thought Luke, Leia and Han would show up. They had to do alot of education in the press (and calling it episode 1) to bring home the point that they wouldn't show up.

So finally, alot of the old and casual fans are getting what they want. The old trio back again and the old ships too. Maybe it really will all work again like the original trilogy. The trailer was certainly pretty good.

The sequel trilogy I would have wanted would have more advanced looking ships. The one thing about the prequels that worked so well was the design was so new and different. It wasn't tired. Bringing back x wings and ties is fun but how original is it all going to be?
