The opening scene is full-on nuts and very fakey looking, but i dunno that you need a sand-dune sailboat being attacked by giant duneworms to look “realistic.” Back in “our world” Milla Jovovich is an elite UN soldier(?) until a desert storm transports her to the monster-hunting world where her team is wiped out and she’s cocooned by skittering creatures in an underground insect Matrix until kidnapped by incredible archer Tony Jaa. She fucks up his shrine and they have a really violent fight, then they join forces and make her an arm-mounted grappling crossbow. “To kill a monster you need a monster.” Lost Boy Ron Perlman joins them, fighting off a stampede with flaming swords, then we go through the kidnapping / friendship thing again to fight a fire-breathing dragon. If I’m making this movie sound unbelievably awesome, that’s only because it is.
