What makes Wallander appealing?

What's the appeal of Mankell's detective, Wallander? He reminds just a bit of Maigret. I like how inductive he is, and how the rest of his life intrudes on his concentration (his father, his daughter, etc.)

I like Kurt Wallander because he seems to be a man with problems we all have; his marriage wasn't very good and his relation with his daughter Linda has been difficult. She on the other hand has chosen her father's profession and she also is a very good detective. I think one other reason I like Wallander is because of the actor who plays his role, Krister Henriksson, in the crime serie on TV. He is just the man for this character. Reading the books you also notice that Wallander develops himself from a lonely and grumpy man in a midlife crisis to a man who also respects and loves his daughter.
