Nope. You're not the only one. When I saw it I was like "These people are either horrible actors or there's something else going on." That's when I figured it out.

I didn't really like that movie too much. It had a few good parts but I had to snort every time I heard something like "those we do not speak of" or "the bad color." But that may have also been from the special added commentary of my father and brother.
