Unless everything we think we know about this film is completely off base, Luke's absence figures heavily into the plot. I'm totally fine with him barely being in it if it makes the story better. We've got two more of these on the way, I don't mind it if we don't get everything all at once.
Yeah, well Mark Hamill isn't getting any younger (and neither am I!) I may be dead before the next 2 come out! ;-)
Anyhow, good trailer. The trailers alone are already better movies than eps 1-3.
