I have mixed feelings about Wallander.
It was one of the first subtitled TV series we watched and recently we realised we'd missed some of them and sat down to watch one. It was so slow and quite dated too, but what put us off the most is we'd not known that over the years, 3 different actors play Wallander. We really only liked Rolf Lassgård in the role, so in the end we gave up watching the shows we'd missed because it was the other actors in the leading role. I would certainly recommend watching the ones starring Rolf Lassgård. Others might feel differently though. One thing though, if you watched the English remake with Kenneth Brannagh as Wallander, the plots are basically just the same, so you'll know 'who done it!
