You were all right, as I expected-- the script/plot/action/acting etc. was mostly ridiculous. However, I managed to enjoy it, at least partially, due to the following reasons.

1. I am a Hell enthusiast (obvious, really ...)
2. I enjoyed the live Voidoids bits (and liked the rest of the soundtrack)
3. I enjoyed the mood/feeling (of the surroundings etc.)
4. I enjoyed the footage, aesthetically speaking (yes, that includes Richard, who, though he could not be said to have acted well, was as charming as always)
