I went with Burnt Offerings. But, basically this is really about the great beginning of Legend of Hell House versus the great ending of Burnt Offerings, because both are terrifically lame movies with one good thing the other doesn't have. But not only one thing. I gave the edge to Burnt Offerings because both films feature a possession angle and I thought Karen Black's possession was better than Pamela Franklin's. Pamela went further, but she also made it silly and over the top. Karen's possession was a little more graceful and... it was actually crucial in "that" ending which I did not see coming. Well, the reveal yes, but not what happened after the reveal, which is classic! Plus, Pamela seems to be doing what had already been done by Julie Harris in The Haunting.
