Very good additions to an already great, but far too short series. Probably the weakest movie in the collection is the first one, "Dark Horizon" -- it attempted some special effects that just didn't deliver, and tries too hard to pick-up where the series left off five years earlier.

The remaining four movies did a much better job of staying true to the spirit of the series, and examined several topics (racism, desire, belonging).

I strongly recommend this set, as well as the TV series that preceded it.
