While not as polished and gripping as the best police dramas out there (with the first series of True Detective as the category benchmark), Springfloden does a good job in most of the departments.
The very beautiful Olivia is a Swedish police academy student who stumbles by chance on an old unsolved murder case that obsessed her father - the detective investigating on it - up until his death. Of course she can't resist the lure of this mystery and embarks herself on an unofficial investigation that will bring a lot of surprises and messes all around Sweden.
The writing and the side stories are well crafted and interestingly enough deal with social issues in developed countries (homeless, children without an economically stable/culturally evolved family). There's also some room for slightly humorous moments that in my opinion just add up points to the realistic tone of the drama.
As a whole I could find very few holes in how the pieces got connected together, yet for some reason or another I couldn't suspend the disbelief: most of the time everything was clearly part of an acted TV fiction. This might be due to the depth of the backstories of the characters we get to know which barely comes to the surface when these characters act. However It's hard to say this is any specific actor's fault (at least the leads showed a proper range): I would instead point the finger to the writing (which may have tried too hard to include cool stuff) or to the direction (which possibly wasn't able to capture the complexity of the characters in an expressive way).
This said Springfloden is a series you can't miss if you are into detective stories because it's more realistic and better executed than the 90% of the genre's other incarnations.
