Also known as Boa this would be a much more appropriate title. The DVD box mentions nothing about a giant, prehistoric snake on the loose, it just tells us about the location.
Anyway, prison on Antarctica, excavation work releases snake from hollow rock, snake eats almost everyone, palaeontologist couple escape. The story there summed up in a sentence, if only the film was over this quickly.
Obvious CGI snake, explosions and aeroplane aside this is awful. One woman has the worst Irish accent in film history but she is the least of your worries.
I cannot recommend this to anybody.
