Pretty good British horror film.
5 December 2004 | by HumanoidOfFleshSee all my reviews

On a remote planet,a group of archaeologists have established a base deep inside a network of caves.While out exploring one day,one of the team,Sandy,is abducted by a monstrous alien that forcibly impregnates her.As the alien fetuses grow inside her,Sandy is driven insane by the need for blood to feed her offspring and starts slaughtering her fellow scientists."Inseminoid" is a cheaply made "Alien" clone,but I don't care.It's a pretty good horror film on its own that kept me on the edge of my seat.There is plenty of gore and a little bit of sleaze,so I wasn't disappointed.The script is weak and the acting is average,but "Inseminoid" is fast-paced,twisted and immensely enjoyable.So if you liked "Galaxy of Terror" or "Forbidden World" give this one a look.Just ignore the negative reviews and check it out.7 out of 10.
