Main characters were not believable. Little plot and lots of 3d video game effects.

A visually stunning movie. The story line was solid but the script and acting fell flat. The main characters were dry and unemotional. Rihanna's character and the special effects characters really carried the movie.

Weak story line,

The story line was predictable and the dialogue was juvenile. The highlights of the movie, which is why I am giving it 2 stars, was the special effects and the part of the movie with Rhianna. Her character and overall performance was hands down the best part of the entire film. It was hard to take the two main characters seriously when they appeared to no more than teenagers yet they were supposed to portray the best in their "field"... not very believable when they were surrounded by a full cast of adult characters. It was like a really bad combination of Star Wars and Avatar.
