I didn't enjoy this episode much. It feels empty, it feels out of character, it feels not scary at all. There is nothing in this episode that you can stop and say "that might happen to me" or "that better be destroyed or we are going to suffer" and even if it is there, the story is presented so harmlessly that in the end you have not been scared at all.
The special effects once again make this episode look bad. The only thing i liked was the idea of being in Africa in the middle of a storm, kind of reminds me of the fear those first explorers might have felt a couple of centuries ago.
