Well I must say I did really enjoy the Search - I liked the locations, and learning some history, and there was some code-cracking elements but nothing we could really take part in as they never really showed you the codes for long enough.
I thought it was pretty badly planned and put across though - I mean there are camera crews all over the place, so as soon as one team arrives in a spot they should see where to go because the others would be highly visible, and what really annoyed me was when they seemed to have no clue about what was happening, and then there was some VT with one of them saying "and then I just thought, ooh what if it's to do with so and so" like they got a HUGE prompt from the crew.
I was pleased that one of the 2 girls won, although I would have liked Marianne to win slightly more

Overall a good series, it was very similar to Codex which I also enjoyed - be entertained and learn some stuff at the same time!
I hope they do something like it again with better challenges and more participation.
Oh, and anyone here win the viewer's challenge? They said they would put up the answer and the winner yesterday but they haven't!
