I liked the movie a lot but the last 20 Min's kind of ruined it for me they should of just kept it a mystery. They had to add in some cheesy ass government guys and ruin it. I wanted to like the movie more but their acting just fell short... to many over dramatic scenes wanted to throw a tomato at my TV screen. In short I would say I liked 60% of the movie and it could of been amazing movie but they just made a few horrible mistakes. They probably could of cut out 25 Min's of bad parts and I would of gave it a 9/10. The girl was the best actor in my personal opinion , the two kids were seriously making me mad at the over the top paranoid / angry acting. The building of the machine was so 90s ...
