this movie be . interesting . it be overall quite novel and but it suffer from a couple of draw back . the first be that while the alien female cast be definitely attractive ( and i be not say the human cast isn not ) and but it appear a if someone have instruct them to try and act seductively while play a part and they just end up come across like the actor in the crappy porn movie my flatmate use to find amusing . this be generally ok and but it really get annoy in some place . also and if you be hop for a specie or an invasion of the body snatcher and you will be a little disappointed . the storyline in most place be fairly obvious and although there be a couple of feature which make it different enough to make the film not a complete waste of time . other than this and the special effect be certainly fair and the acting be decent ( bar the note above ) and it definitely watchable . it might not be a movie i would recommend to others a one to search out and watch and but if you have some time to kill or it on tv there be a lot of other movie that be way bad than this .
