Inconsistent context ruined the movie

Rating: 2/10 (30 April 2008)

I am so sick of movies that are inconsistent and this movie falls right into that category. This brilliant doctor, can set a trap to capture a creature while protecting it from the sun, carefully stocks up on food and maintains power for his house. Unfortunately he has not learnt to carry a side arm (I would have carried about 10), has not learnt to replace every other light in the house with a UV light (the creatures were killed by UV), surely would have rigged a lighting system on top of the house also with UV, and cannot shoot an antelope from further away than 10 feet despite having access to the best weapons on the planet which would have a range of 1km. Not to mention the fact that despite exercising everyday, he struggles to cut himself free from a trap.
Inconsistencies ruin an otherwise potentially good movie.
