HYPOTHESIS: The cast are all retarded
If we look at Bunnyman with fresh eyes and realize that the characters in this movie are all mentally retarded, then this movie becomes a little more realistic. It's the ONLY way this movie works. If we are to believe that anyone with an average IQ would make the choices that they make, the plot falls apart QUICKLY...I mean, like right out the gate fast.
If you haven't watched Bunnyman and you STILL have to watch it, watch it thinking that "these people are unfortunately mentally retarded", this will give you the empathy to at least feel some sort of sympathy for them or care either way.
Unfortunately, I think it was the person who wrote the script that was lacking in mental intelligence...and perhaps even myself for finishing what is on my list for WORST MOVIES EVER YA'LL.
