In Australia, a majority of films have to go through the Australian Film Finance Corporation before production. That usually means that Aussie flicks are underfunded, and Subterano is no exception. I tried to like this film. As an Aussie, I felt that I had a duty to like this film. But I couldn't. The script is terrible, the plot is unsuspenseful and you could really care less about the characters.
Sci-fi wise, Australia has had some success with 'Escape from Jupiter'. That was a children's TV series practically unheard of outside of Australia. And, in reality, Subterano is nothing more than an overbaked form of that, with little in the way of budget and creativity. Avoid this film at all costs. I remember saying that this is, without a doubt, proof that Australia should stay away from science fiction cinema. And I stand by that.
