According to Deadline, Unforgettable's Season 2 ratings averaged 8.2 million viewers, which doesn't sound that bad — especially for summer. (It probably didn't hurt to follow Big Brother on Sundays, particularly after the controversial season they just had.)
Apparently CBS was happy with the return, since Unforgettable was just renewed for Season 3. Deadline says 13 more episodes will air in the summer of 2014.
Are you happy to see more of the show, or had you forgotten that it was even on to begin with?
