Mere words cannot describe how awesomely gnarly "Piranha 3D" is
, how hugely entertaining, and how urgently you must get yourself to the theatre to see it. Like, now.
This is not a joke, by the way. This movie is a complete blast. To borrow a phrase from the kind of B-horror flicks to which "Piranha 3D" is such a loving and effective homage: Run, don't walk.
