Hey Derek, I caught it and thought it great. At first I thought it was a repeat of an attrocious doco of the same or similar name that appeared on one of the commercial chanels a couple of months back.
The presentation was informed and primarily just the facts. This is where they are, this is why they are dangerous, this is what they eat and this is how humans tend to encounter them.
Their conclusion that the humble red back spider was probably the most dangerous I found interesting. It was obviously based on the number of hospitaliasations which is a realistic way of answering such a question.
I was surprised at Weigle's assertion that the only people ever killed by the Central Taipan (Fierce Snake) were snake handlers... because of course is a relatively calm species.
