Great visual effects. The crew was made up of well known characters in these types of movies. The hero or heroine in this case was strong independent and courageous. The story left unanswered questions and moved very quickly at the end. As much as you must suspend belief to enjoy a movie like this, there were still situations that were not believable or did not flow. After the heroine performs a cesarean section on herself she still manages to fight off aliens and perform daring feats of physical endurance. Noomi Repace in my opinion tried too hard and many of her scenes seemed forced. I liked her in "Dragon Tattoo" but she did not fit this part well. Overall a good movie but I expected more.
