I have watched NCIS:LA from the beginning. I love the characters together, and individually. All the couples have been well suited for each other. I am disappointed that after all these years, Callen is given a love interest, and she turns out to be a blonde "thirtysomething". Anna is 15 years younger, so it looks like Callen is going through a mid-life crisis. He has chased her for a while. I was hoping for a more substantial relationship for him with a woman closer to his own age; now that he is a senior. Are there no middle-aged, beautiful, intelligent, talented female actors in Hollywood?
