Lord High Vizier of Nowt
The sad part is it actually had potential.
All of which were made up as a kit of parts from other movies and TV series.
Obvious 'influences' I thought about while watching: the harvesting aliens were The Wraith from Stargate Atlantis driving the semi organic looking robots from the Matrix movies which arrived in the Bloody Big Ships with Huge Shadows we have grown to know and love from V, Independence Day, Childhood's End etc..
The film also had that cheap 1950's morality that I thought 'Hollywood' was growing out of. Cheap laughs at gay characters. The 'slut' - she is referred to as that in the film - being one of the first to die - followed by the only black character. (The fact that he was the most believable and sympathetic character, played by the best actor in the film didn't help the proceedings.) They even managed to squeeze in 'the character getting themselves killed trying to rescue the pet' moment - happily (for once) the pet got eaten too which was probably the only novel moment in the whole script. Sadly the little yapping dog didn't get eaten on screen.
