I felt like the art, at times, left a bit to be desired. Some panels lack detail. It seemed like there were moments captured perfectly and wonderfully, but the time spent on them were to the detriment of other pages. It also seemed like capturing likenesses was the most important concern, and that quite often leads to somewhat stiff art. However, the story and characterization are so well done that the bad pages can't bog them down at all.
How about you guys? Have you been enjoying any of the IDW Trek books? How about Doctor Who? Let me know what you think.
