JJ could learn to let the characters have more time to talk and scenes breathe so the plot makes sense more easily. Star Trek works best when characters have time to interact with each other and talk.
I don't know. The more dialogue you present, the more gotcha moments that are there for the OCD crowd to tear apart.
In another conversation, I mentioned I thought that the movie might be better if we got more of Khan's background. But the downside is the more backstory you put out there presents the opportunity for more errors to be found.
Especially from this crowd.
