I saw this as an MST episode, and it's one of the few where you might actually be able to watch the movie and stay interested if Joel and the bots weren't blabbing away. The commentary is hilarious but the story also manages to be somewhat intriguing.
There are what seem to be obvious flaws in the plot and even the wardrobe and outfitting of the cavemen that make the whole film seem silly until you get a surprise ending that you wouldn't be able to predict. The acting is bad and the cavemen are far too clad, but you don't seem to care entirely I wouldn't recommend actually trying to watch this on it's own, you need MST to make it enjoyable but at least it was a serious film which didn't entirely fail to entertain you and get it's point across.
As a side note, I saw quite a few ideas here that have been used by Jean M Auel in her Clan of the Cave Bear portrayal of the Clan, even down to the name of the people
