Guillermo del Toro has made a movie about people in giant mecha suits battling giant monsters featuring characters like Hercules Hanson and Stacker Pentecost. You're either going to roll your eyes at how stupid those names are or you're going to smile because you know those stupid names are on purpose.
del Toro has placed the bar firmly and visibly at a certain level, folks. Please don't trip over the bar running to a conclusion about what kind of movie this actually is. I had fun watching it as a matinee. Don't drop nearly twenty dollars to see this as a 3D IMAX extravanganza but it's easily worth a 2D matinee. :)
