This is no-budget, no-clue and no-chance film-making.

The performances, apart from those of the lead actors, are often painfully stiff, but presumably the cast had to do a lot of reacting to tennis balls on sticks in green-screen studios.

This isn't a good film ... but it's bizarrely entertaining, even if it is for all the wrong reasons.

Clunky, low-budget sci-fi has some violence, adult themes.
