It should be good.
I like that they're using a mixture of real locations and CGI. There will be more practical effects.
The original three characters should play a prominent role, even if they aren't the stars. It's just a guess, but I think Luke Skywalker has separated from his friends and they go find him, and maybe he does something at the end to save the younger crew, like how Yoda saves Obi-Wan and Anakin in Episode 2.
