The fact that I'm an old man who likes to watch pretty young women in TV shows, is probably irrelevant to the writers, but that does not keep me from stating my disappointment with season 5 up to now (e05).
I do miss Miss Priya Koothrappali. The evolution, fraught with ups and downs, of her interaction with the other characters (especially with the females and also the fibs to her parents) was a delight to watch. She's so much more interesting (and pretty) than old Will Wheaton.
Bring Priya back as a regular, PLEASE!
