I really like this show. I think it is the best of the FBI franchise. Great stories and scripts. Good performances by the actors.
My only major quibble is the locations. It is obviously filmed in Eastern Europe. So when it is meant to be in Italy, Holland, England. Not only are the outside locations glaringly wrong. So are the interiors. The layout of the buildings and the internal features are just so wrong. As someone who has been to most European countries and is a fan of architecture and interior design. It's a huge bug bear.
I realise they can't move the production all over Europe. But surely there must be something they can do other than sticking a red telephone box and a black taxi in the street to pass for London, when you'd never find those buildings west of Poland.
I'm sure most of the American audience is fooled, but most Europeans spot these things immediately.
