"Impossible Planet" and "The Satan Pit" by Matt Jones.

A good old fashioned sci-fi movie, it was one part Aliens (blue collar crew in space), one part The Abyss, (with all the attendant, Nietschzean overtones), and a little sprinkling of Star Trek TOS's "Wolf in the Fold" (the "original" evil with many names on many planets--including "Satan," on earth--goes jumping from body to body).

One thing is clear: Davies really digs James Cameron.

Production values on this one were absolutely astounding. (Including a brilliant CGI devil.) The regulars and guest cast were strong, particularly Will Thorpe as Toby.

They should do more stuff like this. A lot more stuff like this, in fact.
