Dealing with plot holes

Rating: Null/10 (17 November 2004)

I watched the movie and greatly enjoyed it. I am not 13 :-)
much has been made of the plot holes in the movie, but they are not so big.
The rapid gestation of the 'Chest Burster'
This can be dealt with in two ways: The Predators have been using the Aliens for this purpose for some time. The Aliens get characteristics of the host creature. The Predators originally could have used various host creatures to produce the characteristics of a rapid gestation period Chest Burster. Remember the four Alien movies all had creatures from the same batch, so would have had the same gestation period).
The Predators were very technologically advanced, assume that they would have had genetic engineering technology, and could have engineered rapid gestation into the Aliens. This would have suited the Predators for their rituals, and suited the Aliens because it would make them more virulent.
The Alliance between the Predator and Alexa.
Take this in context. The Predators were used to a set number of hosts being implanted (remember the sacrificial chamber), as well as a set number of Predators. The Humans were more numerous, therefore the aliens were in too great a concentration. The last Predator was alone and outnumbered. The 'My Enemy's Enemy is my friend' comment very much applied to him.
Alexa running around in a T-Shirt in the Antarctic cold.
Now I am pretty sure there was a nearby explosion which was melting the ice. This would have provided enough heat for her, For a while at least.
There are shortfalls in the plot, but I'll have to wait until I see the movie in English. The French version I saw was OK, but any number of small details could have passed me by.
