If you're basing the CG just on the trailers, you're missing out. I will say there are some spots where the CG is wonky, but overall its passable and never took me out of the story.
And you know that they will never say Rian isn't allowed back, especially in public, rather they just won't mention him again.
As for Rogue Squadron, my understanding is its still happening in one form or another, but is pushed off.
And no I don't think you're joking. But I do think you'll like this movie overall, and it should be seen in theaters. But whether you wait until it comes out on digital at the end of the year, or you go see it in theaters, you should watch it.
