Wow, strong disagree here. I think that Anu is the first good match for Raj they've ever had on this show. My only grievance with that relationship is that I wish that it could have happened organically, as opposed to him giving up on finding love, and asking for his parents to arrange something for him.
I love her. I also love the idea that Raj gave up on love, was willing to settle for whomever his parents chose only to find they might have found his one true love.
