So after reading some of the other reviews and complaints about accents I don't know what everyone's problem is. I am not from the UK I'm Australian and had no problem understanding the accents. Maybe because I watch a lot of TV Series with a wide range of accents but seriously if people are having problems with this maybe they should learn to appreciate that other parts of the world speak differently.
Anyway, I really enjoyed the mostly realistic story. I found the characters relatable and likeable. Which speaks to the actors skills.
It was an enjoyable journey being convinced one suspect committed the crime and then a different one the next episode. I always thoroughly enjoy a female lead also.
Here's hoping there will be a season 2.
