Mother's Day (1980)

I love late 1970s/ early 1980s horror movies, and was excited about this.  But I guess I should have looked at the description since I do not like movies that revolve around victimizing women and sexual assault.

Three women who went to college together go on a yearly outing to camp in the woods and are kidnapped by two backwoods brothers with a twisted, domineering mother. 

After being assaulted, one of the woman dies and the other two decide to take revenge for their friend.

The whole movie just makes you feel icky and I didn't enjoy it.  The only thing I did like was the scene of a pseudo Bigfoot vaulting out of the bushes, which came out of nowhere and was amusing though it was supposed to be scary.
