My favorites from that era were all horror-comedies. Leslie Vernon and Slither are good picks from this.
Have you seen Fido (2006)? Billy Connolly, Carrie-Anne Moss, Dylan Baker, Tim Blake Nelson, it's a mashup of the old Lassie TV series and Night of the Living Dead, where zombies are domesticated and turned into free labor. I don't think I've ever seen it brought up on horror forums so maybe it slipped through the cracks, idk.
