While the plot and the script follow the excellent book upon which this is based fairly well, the end results fall short of the mark.
Jessa looks kinda like she's described in the book, but the other characters aren't really recognizable, even Han and Chewie. While the ship renditions are fairly good, the only thing they got right was the Falcon -- there weren't any TIEs in the novel, and those little fighters in the comic aren't Z-95s.
The art is too childish, and the words are too big, and the coloring and detail is a bit dull. Still, all of this is somewhat overcome by a fairly exciting story and a fast pace.
Another plus is the low price. If you're into Star Wars, it's worth the money.
