I'll keep this short and sweet. This was obviously made for hardcore Doctor X fans, as the three little 6-"episode" mini dramas were. This, though, unlike those, was written by the same guy who writes Doctor X, so it has the same humor as the original series. It's a full 100 minutes long, too, and the story is cohesive, endearing, and funny, all you want from Doctor X spinoffs. It also has some great new cast members, among them a totally adorable little girl of unknown paternal origins, and guest appearances by our beloved usual suspects, even a brief sighting of Michiko and Akira.
If you like Doctor X, especially if you are waiting for Season 6 or 7 or 8 to be subbed depending on when you see this, you'll probably thoroughly enjoy the shenanigans of this one. It's a little more racy (only a little, though), and more focused on comedy than all else though it does present an interesting couple of medical cases amidst the clamor.
