What to do when your marriage is on the rocks? Go camping!

That's what the attractive couple do in this remake of an offbeat 1970s Australian horror flick. Of course, they bring along a pile of expensive camping gear in their expensive SUV. Wouldn't ya know, that includes a spear gun and a scoped rifle. Hmmm.

They are supposed to meet another couple. But on their way to the beach, they get lost and, ignoring all kinds of warnings, drive into a "keep out" forest. But there's a beach! Let's camp here!

Let the bickering begin. Few couples are so in dire need of a divorce as these two. She hates nature. He is tone deaf to her feelings. She sprays insecticide on ant hills. He throws a beer bottle into the ocean and shatters it with his rifle. They have contempt for their natural surroundings. Hmmm.

Things start to happen. Nature's revenge? Oh yes, but in subtle ways that serve to incite their nastiness to each other. What about that other family camping a few miles away? And what about the dead dugong (manatee) on the beach? Is it really dead?

This is not going to end well.

The Long Weekend, also known as Nature's Grave, is a well made and gripping horror flick, especially because most of it is filmed in broad daylight. It has tense set pieces and several jump moments.

Mainly, it is one of a kind, although it borrows from The Birds. It will keep your attention if you give it a chance.
