It's been a while since i've read the Edgar Allan Poe story, but i really don't recall the lesbian shower scene. I should read it again.
This adaptation is as loose as they come, and it's a mess. Also, the ADR is off; it doesn't synch up with what we see on screen at the end. But by then, it probably doesn't matter much.
The ghost cat sounds like an evil sheep. I guess that's sort of amusing.
