Notes: CBS-TV. The Butler family (John, Kim, their son Greg, daughter Katie, and dog Digger) explores the Amazon and a whirlpool sucks them to a prehistoric land with dinos and cavepeople. A baby stegosaur named Glump befriends them.

Commentary: How come my family never went exploring uncharted portions of South America? More Spaghettios, Grandma!

Notes: NBC-TV. Ranger Rick Marshall, his brats Will and Holly, and his canoe go over a waterfall, but no one dies. They get sucked into a time vortex. Unwisely we follow them. Holly names a baby brontosaur Dopey, a triceratops Spike, a baby allosaur Junior, a tyrannosaur Grumpy, a two-headed sea creature Lulu, a flame-breathing dimetrodon Torchy, an adult brontosaur Emily, and an adult allosaur Big Alice. These morons encounter a hirsute tribe of "Pakuni" and an advanced race of "Sleestacks." After two seasons, Spenser Milligan (who played Rick) bailed. On the show, he was killed off by an earthquake, and replaced by his brother, Uncle Jack, who had been searching for them all and was similarly "vortexed."

Commentary: Reprehensible.
