Just plain fine.

I liked this episode the best in this season. Nevertheless, new episodes don't and won't grasp the intonations of the very first seasons. The show has evolved along with the characters. It would have been really hard to keep Howard's weird and incredibly funny personality for the whole 10 season. So that he is married now and expecting his second child. He becomes something else, almost a decent husband. Other characters took the shape of something else as well. But every show must go in certain direction and evolve as a whole. I consider this show as an epic journey. The one that carefully and intelligibly used great jokes(along with great cast), and now that all the authenticity have been left behind, it floats somewhere between an average and good one now.
