Earth vs. The Spider is the Best Bad Movie Ever.
Seriously, the spider gargles at people, the mother tells the daughter not to worry about the fact that she lost the necklace her recently (As in, last week) deceased father gave her because she needs to do her homework, there's gratuitous shots of oiled up muscular men digging, and a ton of other little lines and shots that never fail to incite a solid "Wait...what?".
God I love that movie...
EDIT: If anyone is wondering, it's not a cheapo Sci-fi (Sy-Fy?) channel show. It was made in '58, and has that wonderful fifties plastic vibe to it. They actually wake up the stunned spider at one point because those wild kids were playing their crazy rock and roll music too loud.
(Think Buddy Holly preformed badly by people in their thirties pretending to be in high school)
