I have to admit that I too have been underwhelmed so far. But there is one story that I am hoping they will tackle if not this "year" (and I'm not speaking of a calendar year but of a 12 issue stretch) then next. It is one of the classic Trek stories that will be most fundamentally changed on multiple levels by the changes to the timeline, and that is... Amok Time!
Frankly how they handle that story will do a lot to tell me whether or not this is a series worth bothering with.
