Eh, not everybody likes the same things, thank goodness.
I can see where some folks might decide to give it a miss. Personally, thought it was brilliant.

The giant blood fountain and ElisaSue’s dissolving into a splotch on the pavement was, for me, a release. The film had, up to that point, been riding the cliff edge of being so disturbing it would tip into comedy unintentionally. That last 40 minutes was telling the audience “it’s ok. This is SUPPOSED to be black humor.” It was the final thing that made this a grand allegory, rather than a ‘story’ with ‘people’.
