I hope that this series is as good as its premise and I wish you
every success but, I implore you, please remember not to fall into
the trap of all prehistoric themed programmes - namely portraying
theory as absolute fact. A simple quantification of statements such
"It's possible that....." or maybe "One theory suggests......" etc
etc. would be spot on, as opposed to "These animals migrated north in
August......" or similar. It's a small thing that makes a massive
difference to the viability of the programme.
