Why didn't......(spoiler)

Rating: 6/10 (15 August 2004)

I saw the movie today and can't figure out 2 things:
1. Why didn't the baby alien die inside the Predator when the queen impaled him with her huge tail near the end???
2. Why didn't the other Predators see that there was an alien inside the dead predator by using their infrared vision???
The ending definitely had a cheese factor of 10!
Other than that, the movie was good, I mean, I don't think it was the worst movie and it wasn't the best either.... An extra 1/2 hour of movie time probably would have made it much better!! I felt like it was too rushed.
