I rather enjoyed this episode. First of all, we have the evil hologram who entices the Doc to come visit. We know, it's going to be more than a social visit, as the Doc assumes. The guy playing the bad hologram is very good and nutty as a overstuffed fruitcake. Meanwhile, back at the ranch, Seven is contributing amazing scientific knowledge, upgrading Voyager at every turn. Ding Dong Harry is taken with her and participates in one of the most uncomfortable scenes ever. It is also utterly hilarious. There was just a lot going on, and if not too carefully thought about, is some fun.
