Unfortunately it is based on the less effective ending of the first movie. If you haven't watched the first part (Descend), you might want to continue with the second paragraph, because I'm going to write about the two different endings of part 1. So here goes: The original ending of Descend was that the sole survivor we know of, is escaping the caves and the monsters, running in the forest, only to wake up and to realize that it was all a dream and she is still in the caves. The other ending stops, when we see her running through the woods, letting us to believe she did escape.
And this where this movie starts off. So you could say, that this diminishes the impact of the original movie. If you can overcome that, then you will enjoy the second part, that is actually pretty good and scary. As you can imagine, it does make sense to have seen the first one, for quite some reasons (though I won't reveal them here, so you can enjoy them in the movie) :o)
