Well indeed, ahem. A semi-gothic ghost story in outer space, with Dr Crusher getting all hot and bothered. In my more caustic moments I have been known to describe the less riveting TNG episodes as 'a bit like social work in outer space' but this is something different again.
This episode sits incongruously alongside the usual TNG fare, so naturally some fans will just hate it. On the other hand the few 10/10 reviews each have their reasons. According to one, if you happen not to like it, that would be an attack on female sexuality.
I found it moderately interesting but not especially compelling; since there are plenty of TNG episodes that are like that (if you try enough slightly different things there are bound to be a few that fall flat) then it shouldn't come as a massive disappointment if you happen not to like it.
in point of fact a few things did irritate me, but they were not the ones you might expect; first there is a character that has an accent that I can only describe as belonging to an Irishman who has been told to talk a bit Scottish; a more mangled sound you have never heard. Second when someone is attacked and they fall over, they are immediately declared 'dead' with no attempt whatsoever made to resuscitate them. Very un-TNG, that. It isn't explained how the Howard family line even came to be; the candidates are alien incest or more than one relationship, I suppose.
There also isn't much of a sub-plot in this episode; I thought that such things were almost compulsory.
Maybe I read it wrong, but the other gravestone (other than the one that says 'McFly') appeared to me like it might read 'Nadir'; I didn't think it was that bad, but for some this would sum up this episode nicely.
