I don't remember this well enough to rate.

This originally aired in 1974-77, which is kind of before my time (I was born in 1975). But I used to watch it in reruns on Saturday mornings for awhile, probably in the mid 80s. Anyway, this guy named Rick Marshall, along with his son Will and daughter Holly, were on a camping trip and got stranded in some weird place full of dinosaurs, and there were some sort of Saurian humanoids called Sleestaks, and one guy named Enik who looked like a Sleestak but wasn't. Because they were evil, primitive, scary guys, and he was an intelligent, civilized guy who befriended the humans.
Anyway, it was an odd little show, not great production values or anything, kinda cheesy and stuff. Of course it was a Sid & Marty Krofft production, and it was many years after seeing this before I ever heard of them, as far as I recall. And I know they did a bunch of other cheesy shows back in the 70s, but this is the only one I ever got to see, I think. But I'd like to see this again someday, write up a proper review.
In 2009 there was a comedy movie based on the show.
