Having survived (just) the grim awefulness that was the Thorne 2 parter this was a very welcome relief !!
I confess I had never heard of Zen and so came to this as a dewey eyed virgin..
..It was a delight,filmed in and around Rome it had plenty of authentic atmosphere without becoming a travel promotion,developing story arcs - Zen's Affair/the Mysterious Cabal/Devious Political Machinations all wrapped up in interesting stories.
I found the first episode "Vendetta" the weakest and to start with Rufus Sewell's Zen a bit of a plank ! The first episode in anything tends to be the most difficult, but by the end I was well on board and appreciating the understated,wryly amusing Zen.
As said elsewhere I also found the use of British regional accents a bit disconcerting,after a while you get used to them but why do it in the first place ? OK you don't want it to sound lika da italiano ica-cream sales convention but .... By the way I had to laugh at the puzzled comments that two of the female leads had Italian accents - well thats because they are Italian !
I would strongly recomend watching the "making of world of Zen" feature (but only afterwards !) ,as good as an extra episode and the sheer joy of making Zen comes across very strongly..
If you like warm, intelligent,interesting crime drama then this is a Pizza to savour.....If you prefer cold greasy chips,well,back to Thorne.
