I saw it and the Scientology comparisons are thin at best. Saying that it's based on Scientology teachings because it has things like "Man versus Nature" or that it's got a volcano is so laughingly stupid that the author of that article should probably be lobotomized for making us all dumber for reading his ****.
Now, about the actual movie?
It's ok. It's not great, not terrible. Just nothing to write home about. It's certainly beautifully shot. They tried to invent a new accent for the characters in the movie, but quite frankly that was more distracting than cool. Especially since Will and his son kept falling out of the accent at times. The problem with making a movie like this is that when you essentially have only two actors on screen through 95% of the film, they better be damn fine actors. Will Smith is pretty good, he's had some good roles. Jaden .. Jaden is more there than anything. Just being present on screen is just not enough. The plot is pretty simple, a father/son situation where they are trying to bridge some distance that developed between them over time and after the death the other sibling in the family. It's got some good action moments, some cool scifi tech, but ultimately is pretty mediocre as movies go.
Some problems I had on the plot and setup .. if the Ursa can smell fear in pheromones, why do you need to train people to not be afraid? Just create an entirely self contained and pressurized armor system that prevents the pheromones from escaping into the air. Now your army is entirely invisible to the enemy 100% of the time. The saber weapons are kind of cool, but impractical. I didn't see a single gun the entire movie. Now, you would probably want to keep a saber weapon for hand to hand if it comes to that. BUT, pick up a ****ing gun to shoot the Ursa at a distance to prevent it's size and speed from being such an advantage. Seriously. Even the Ursa was shooting stuff at people more than they shot back.
Definitely catch it on Netflix, or a matinee to a lesser degree.
