I did a few then went back and removed them all. They just don't "get it" and view it as a welcome to open the door and spam me with crap I'm not interested in. At one point I had "liked" a show and it worked well, I got reminders that it was on and new vs. a repeat, and links to behind the scenes pieces. However I then did the same to another and it was nothing but spam for other shows on the same network, after that, no show gets "liked" anymore. I could be more granular as to the settings for the "like" but I shouldn't have to jump through hoops to do that.
