I completely agree, and that's why I'm going to give it the credit it deserves (on a personal level obviously) by grabbing a copy on DVD this October and adding it to my movie lineup for this year.
Me too, first viewing I shunned as "this isn't Halloween", second viewing, I enjoyed it just taking it's story for what it is.
However, it's lack of popularity, I have to go to certain stores to try and find it, Targets and Walmarts will never have it.
