Ugh, I hate writing negative reviews, but this really is not worth your time. I say that as a staunch supporter of the Disney Era of Star Wars. In fact, unless you have to read everything, avoid one. It contradicts something we see in The Force Awakens. I won't mention it, so as to avoid spoilers in this review, but it totally ruined this mini-series for me. You do get a little insight into Han's relationship with Leia and Ben at this point in the timeline, but nothing you couldn't have already deduced from the films.
My rating: 2 Stars
