As I said this is about the Norwegian camp before the opening scene of the the original and the helicopter chasing the dog scene, so you have an idea things are not going to go well.....
It starts with a spaceship being found and an alien life form found buried in the ice close by, experts are brought in and the body recovered, escapes and then the shenanigans begin. The creature can duplicate living tissue but nothing man made (good idea about teeth and fillings is used).
It's been a while since I've seen the original but I have fond memories of it and of it being suspenseful, good acting and good effects for the time and the excellent ending.....
.....this is less so and gets right to an alien slasher movie, screaming, paranoia, distrust, flame-throwers and bad dental hygiene but as a popcorn movie it's not bad, good alien effects, screaming and running, gore and action....
I didn't recognise anybody in the cast that well apart from a bad guy from the first Under Siege but that's not really an issue as some of the cast are quite good regardless, there are a mixture of Norwegians and Americans at the base and there are subtitles but nationality goes out the window when being chased down a corridor by a two headed monster with six limbs that you used to know....
Worth a watch and they do the ending properly in the credits......
