Yeah, H20 gives me chills in several places, particularly that sequence. It's so adrenaline-pumping. You're really rooting for Laurie in that movie. 
That scene, and when Laurie and Michael finally look into each others' eyes through the door window. 
She's such a strongly written female character in H20, flaws and all. A female role you barely see written anymore. She's divorced, she's an alcoholic, her son hates her... She's pretty much a fully realized human being, from a writing standpoint. You can practically 
feel the history of her life from 1978 to 1998. 
I think H20 is 
devastatingly underrated. One of my favorite horror movies ever. It clocks in at exactly 80 minutes, and it's an entertaining, engrossing adventure every time I watch it.
