Herzog's documentaries are always worth a shot. They don't always turn out great, but Herzog himself is such a peculiar figure that there's always a chance of some fun quotes or interesting angles. The same goes for La Soufrière, a somewhat haphazard doc about a volcano about to burst.
When Herzog hears a volcano is about to go off on Guadeloupe, threatening to destroy the island, he gathers a crew to document the event. He finds a deserted island, except for one man who decided to stay behind. That sounds like a great story, sadly, it turns out to be somewhat less exciting.
Not so much that in the end the crisis is averted (the volcano never erupts), but the guy they find isn't really all that interesting. He becomes the primary subject of the documentary, but he just goes on about God and whatnot. Still, Herzog shoots some very nice pictures of the island and the deserted towns are pretty haunting. Decent.
