I guess the warning is in the title. It's more about the team filming the volcano than it is about the actual volcano. Far to many close up shots with the film crews faces in it. The only way to watch it is with remote in hand so you can fast forward the 'guff' to get to the good stuff. There were so many interesting characters in this show but the focus was almost entirely on the narrator. It seemed a little self-congratulatory. There are so many interesting aspects of a volcano and it's effects on a populace to be explored and this show focuses too much on the narrator and team, such a shame. Next time a little less you and more them please.
