ATTACK OF THE CRAB MONSTERS (1957): http://radiation-scarred-reviews.blogspot.com/2009/12/attack-of-crab-monsters-1957.html
"Soon it's just Hank, Martha, Dale, and Momma Crab on a tiny spit of island. Hank topples a radio tower (where was this thing still drawing power from?) on to Momma Crab, frying himself and sending thousands of Marylanders into salivary fits."
KINGDOM OF THE SPIDERS (1977): http://radiation-scarred-reviews.blogspot.com/2009/12/kingdom-of-spiders-1977.html
"I should have warned you before, this movie is dangerously cheesy. This is, of course, during William Shatner's post-Star Trek days, and well before he came to grips with being a walking parody of himself, but he gives a good performance nonetheless. Actually, intensely watchable and a lot of fun."
