The caution and hesitancy I had heading into Star Trek proved to be mostly unfounded. Unfortunately, that same caution and hesitancy I had for the first one ended up having been justified on J.J. Abrams's second time around as the man at the helm of the franchise. Star Trek Into Darkness (here on Blu-ray or to rent on demand) wasn't bad, exactly, but it had some major issues, something common in J.J. Abrams's works.
Honestly, the good in retrospect seems far outweighed by the bad. The things that stick out--Karl Urban's tone-deaf turn, the comically terrible opening that was basically a scene that belonged in the bastard step-child of an Avatar/Indiana Jones and the Kingdom of the Crystal Skulls broken marriage, the meandering repurposing of the Wrath of Khan plot, Chris Pine just not quite having the gravitas to pull off Kirk (regardless of your actual feelings about the original Captain)--ring a lot more loudly in my mind than the good--Alice Eve, Zoe Saldana, Zachary Quinto, Benedict Cumberbatch, Peter Weller.
In the end, it just didn't quite work.
