If you are going to see this, see it in 3 D or Imax because.....for me, it was lacking and took 3/4's of the movie to get to it. It was like battlefield LA where it just took to long for the show to get interesting. The majority of the film is 15 year old kids...but the special effects are great, so for those effects, 3D or imax would be a better experience than reg screen.
Fun entertainment...I couldn't give it 5 stars because a lot of the action was hard to follow, they made it go by so fast. A must see on the big screen for the special effects. Stay through the credits for a teaser on the sequel
