I remember watching a movie a while ago about "intelligent" dog like aliens with like a spike or weapons in their tail (like a chimera) who had their home planet colonized by humans.
The humans nearly wiped them out but a few survived and the humans set up a perimeter grid to keep them out - movie is about how the protagonist has his family (wife and child) killed by the alien/s when they attack whilst he is off world. They break through the defences and revenge for the attack on their species - rest of the story is about how the protagonist hunts down the alien that killed his family.
Really good sci-fi movie that makes you think about how the aliens felt while their world was being wiped out just to make room for the humans.
Anyone know the name of this movie?
A bit of a cross between pitch black and star ship trooper style - but it is not Starship Troopers.
