First of all,i'd like to start with the actors.The lead actors were not that bad,I'd characterize them decent especially Zack Ward who I think is a bit underrated.On the other hand The supporting cast were really awful and with the poor dialogues they seem ridiculous.With such a low budget the effects of the film were at least tolerable and I really like the suit and the strange aliens even if the place was too 'earthly' for an isolated planet on the space.On the contrary I can't miss to comment on the title of the movie which is really unfitted as there are no battles on the movie...To conclude I find this movie OK if you just want to pass your time,although don't have any expectations of watching a film full of action,impressive effects and great acting.
