Being produced, written and directed by Hans Rosenfeldt, a Swedish screenwriter and creator of the series Bron/Broen aka The Bridge (adapted as The Tunnel for UK audiences), Marcella is a good example in bringing related undertones and approaches into the UK context. True, the plot includes some doubtfulness and the characters are not so sophisticated and bright-line as Saga Norén and Martin Rohde, but the series is still thrilling and interesting to follow, one can ponder on and over several events and issues.
The wrongdoer was on my list of suspects, but I did not guess the person too early, that is another additional point from me (I have watched hundreds of crime series and, in some cases, the solution is too plain). The cast is even and realistic, there is no one leading role/character shining over the others, as modern police work is always team-work (sometimes "forgotten" by US filmmakers). So, although the series contains hardly any wow! or novel effects, it is still a decent creation to follow, unless you dislike the framework and depiction in Nordic series.
