I like to think of myself as someone who has a pretty strong interest in serial killers, and while I do not consider myself to be an authority on the subject of such things, I am able to tell the difference in fact and misinformation. I use the term "misinformation" as that is what I feel you are doing in your promotion of the film, "Primeval".
The film concerns an animal, or the legend of such. A serial killer kills with a distinct need to do so, be it sexual, "fun", or simply just plain crazy in the head. An animal, however, kills on instinct and either by threat/defense or hunger. "Gustave" is not a person, just the name given to this animal by the locals. Don't try to tell the public otherwise. It's misleading and insults the subject of serial killers in general.
Just call it "Lake Placid 2". We won't actually care if it really is or not, but at least we'll have a better idea of what we're getting into. Thanks.
