I was a huge fan of Poliakoff and Shooting The Past is superb but his latest offerings have been very poor. Almost forgetting what made him great in the first place.See also: Stephen Poliakoff. But at least Jed Mercurio stuff is fun to watch instead of Poliakoff's dreary mannered shite
Not television but Don Winslow has gone the same way. Wrote some fantastic novels but now he's allowed to get away with overblown cliched nonsense.
