Spoiler: Good, but plot holes predominate

Rating: Null/10 (16 August 2004)

***Spoilers***
I thought the movie was decent, but I think a lot more work was needed on this script:
First, the basic premise is that there is a pyramid 2000 feet below the ice on an island off of Antarctica. They send a drilling team to reach the pyramid, and find that it is under an abandoned whaling station. My question is, how the heck is the whaling station so high above sea level or the pyramid so far below it? It doesn't make sense.
Second, one of the first "scares" of the movie has to do with a penguin. What is a penguin doing far from the ocean in an abandoned building in the middle of the Antarctic winter?
Third, there are many times when people are shown with much less protective gear than would be required by the Antarctic winter.
Fourth, if the population of the whaling station mysteriously disappeared a century ago, and the Predators have been coming here every hundred years, why were the people in the sacrificial chamber ancient Aztecs? Shouldn't the corpses been of the people from the whaling station?
These are only a few examples of the plot problems. I mean come on, how hard is it to write a plot that doesn't have holes. Don't these guys have proofreaders?
As far as the action went, it was enjoyable but mediocre. There was too much focus on the humans, and too little focus on the Predators. This film needed more balance.
