This is not worth a full-fledged review (but if you want want I think I could be persuaded to write one up). In short I didn't like it. It was 100% speculative but presented as a documentary and fact. It wasn't until the very end that they came clean, so it had the feel of Blair Witch, or X-Files, or some Loch Ness Monster unveiling. Quite disappointing.

They referenced how many unrelated cultures had "dragons" but did nothing to explain how that might be. I was rather hoping they would have explored a more fantastical angle to dragons, accepting they are legendary and mythical and exploring what it would be like if the had existed as we expected them to, not taking an evolutionary view that they co-existed with dinosaurs and managed to survive the KT event.

So if you missed it, you didn't miss anything, you saved yourself some time. I expect to be paid for my sacrifice. ;P
