If you're 12 years old and don't care about anything except CGI battle scenes where you can't tell which of the billions of confused pixels are on which team then this is the movie for you.
I guess there was a storyline there, but the "look what we can think of" interminably pointless CGI displays had me so bored by the time they got around to it I was simply too bored to care.
First the plot, THEN show off your technology...but then I'm not 12 years old.
Too bad.... wanted to see Jason act... not just in a minor supporting role to the graphics.
