Your expert in all things ratings. :)
@mpflipper Why make Higgins female: Lenkov stated in an interview that he saw the original series as a boys club and wanted a female voice to be present in the new version. However. He also wanted to keep the close military ties and bond Magnum, Rick, and TC share(d) so that left Higgins. I hope I'm wrong, I really, really, do but the fact Perdita Weeks' Higgins and Jay Hernandez's Magnum are so close in age *and* practically living together already, kinda has the writing on the wall of a whole romantic subplot. (please, oh TV gods, let me be wrong).
@Silver Surfer: The original idea (from a couple of years ago) was to continue the series with Lily as the main character. It all kind of fell apart however (not sure why) and a complete reboot was commissioned instead.
@mistyblue2001 Star Trek Discovery only airs on CBS All Access. The grid above is for the five US over-the-air networks.
@viscera693028 The Big Bang Theory and Roseanne do not air on the same night, they are not in direct competition. Different nights will have a different spread of viewers. It's the same reason NCIS will have a 1.2 rating and 12 million viewers while Chicago PD can have that same 1.2 but only draw 6 million viewers.
