Here we are witnessing the resurrection of the emperor, who does this through bonus body he keeps in the fridge but also with followers, what he intended to do with Luke at the time of the sixth film, to join the dark side to take possession of his body.
And grumpy grandpa full of beautiful shots not including that convert Luke to the dark side permanently. It also assists in the creation of the new toy death of Palpatine, the destroyers of worlds so large reactors on legs, which vitrify the planets. A kind of Death Star in much slower and cheap.
There or it goes way is at the drawings, very dark and old-school. We must adhere to, it's really special, but it sticks to the atmosphere very very dark history.
Well there are a few points that goes wrong, no mention of Mara Jade or what happened in the cycle of Thrawn, probably because the novels of Zane had not been converted into strip drawn at the time.
