This is very amusing... So far, just because of the inclusion of a medical professional as a character, we have assumptions of: (A) It being a soap opera(!). (B) Predators killing injured and sick characters. (C) Pure action, even though people have been cursing this film out for not including character development. (D) That the film must be like 'Stargate' happens to be. What if that character is on a vacation and just happens to get involved in the story? What if they are there to draw conclusions on how the creatures are multiplying, by using their profession's knowledge? What if they only appear on screen for five minutes, in the aftermath of an infestation and their only scene is being dragged up to the ceiling? This film is great! It has to be one of the few in existence where its supposed fans automatically assume the worse, castigate it for being boring without proof and then pronounce it as being superficial and only having action scenes, when the next piece of news comes up! Amazing!
