Ok, I guess?
Abrams is capable of directing a Star Wars movie, Into Darkness was a much better SW than Star Trek movie. It all stands and falls with the script.
There are some good signs and some pretty bad signs for now - Palpatine/Imperator coming back from the dead was pretty concerning for me and screamed of creative blackout.
I don't have a problem with the old trio having roles though, as long as they don't focus the whole story around them.
They have so many great novels and games to draw inspiration from, I hope they will use/write something, that manages to bring Star Wars back to the pre Ep I times or at least lift the quality of the franchise to an adequate level where its not painful to watch.
