I can see why it was only an hour long. They didn't have much, but I do think they are on to something. The underwater stuff didn't impress me (reminds me of something similar off the coast of Japan), but the evidence for a buried city is strong. Atlantis is still Crete as far as I'm concerned, though; nothing much here to convince me otherwise yet.
I doubt it's create, too many inconsistencies. For one thing, the Minoans survived the eruption of Thera. The shape is all wrong too.
