I've got the collection, and I think it was a great show in all. Instead of a load of faux sci fi, this one actually does do very well all the way through in keeping a consistent backing. The characters are very good generally, especially as the show goes on. I'm not completely thrilled about the ending, which I will state outright is not bad, but simply as I think it left a lot of open ends. However there are some very good twists and it is in all pretty unique, which is saying something!
Probably the worst bit is the lack of a 'play all' option on the dvds (unforgivable in this day and age) and if that is the worst complaint one can have then itere is a lot going for it!
