I saw this the year it was released, and it was interesting, but a little odd at some points.
The basic part of the story is:
The bug is like the soul of the guy, kind of controls any person he crawls into, and that's why the character is always able to live, I think...
But the thing with the Woman & her daughter is that it follows the story of the bug, in which the bug/ man, could never find a woman that would LOVE him, so he kept coming back (the same age) and would try to get the next decendent to fall in love with him, but it never works out, so he usually kills the mother, keeps her in the coffin in the basement, and takes the daughter away, where she'll have no memory of her mother, then one day fall in love with him when she's older....
It's kind of grotesque if you think about it, but it was a nice story...
