Probably one of the worst sci-fi movies of the last 20 years. The "idea" of the movie was fine. The acting and directing were terrible. Can't remember the last time I saw a movie completely devoid of character like this. The CGI of animals was laugh out loud comical. The "Shimmer" and plant life may have looked better on the big screen but not at home. Somebody did a great job of conning Natalie Portman into this so I upped my score to a 2. Good thing this wasn't her first movie or she'd be waiting tables at IHOP now.
