I appreciated the humour, even though I wasn't aware of the inspirational source, but I still don't think the writing was particularly good. Fun, yes, with some interesting ideas, but hardly an oscar winning effort. After all, Barb Wire was loosely based on Casablanca and they are on record as my favourite and most hated films of all time
Having said that, you may have given me reason to re-evaluate my criteria for good or bad writing. After all, I'm a huge fan of the Evil Dead films and while I'll often quote them, I've never really considered whether the writing qualifies as good or bad.
At least they're all better than the [insert genre] Movie "parodies."
