They already referenced 5.0 in the pilot, where the characters once sang the Magnum theme.
This was pretty slight, but I liked it enough to watch next week.
The casting was good* - always glad to see Sung Kang.
Mainly, though, this is right in line with CBS's apparent overall programming strategy: rely upon police procedurals and/or the leveraging of familiar old properties to produce anodyne "dramas" in hopes of reassuring and holding on to their aging audience: CSI, NCIS, STD, Hawaii Five 0, Blue Bloods...
*By which I mean, every episode should feature Perdita Weeks doing yoga with that self-satisfied half smile.
