Well the Hollywood Reporter review was positive, I have to see it with my own eyes before dismissing it out of hand, if this is a duff entry in the series than thats really sad, because its most probably the last one.
As for Q appearing in a future installment... I don't know Q is a very tv-ish creation, he is all but winking at the camera in the show, all the Q episodes except the Borg one have been goofy 'Trouble with Tribbles' types, enjoyable but I can't imagine that stuff on the big screen. Bring back the Borg I say for one last decisive humungous battle, destroy the bastards once and for all.
