Probably NCIS. I not only watch it weekly, but I often catch reruns during the day when there is nothing else on.
I don't like t.v. Most shows make me wanna gouge out my ears, glue my eyes shut or vomit! If I watch anything it's cartoons, Judge Lake, Judge Judy or something similar. I found Star Trek interesting also but only with age. I hated it when I was younger.
Family guy I suppose and Rock & Morty.
I don't subscribe to cable or dish. But I do have the complete series of Two and a Half Men on DVD. I probably watch that more than anything .
My current favorite is The Good Doctor. (And even though I detest most match shows like The Bachelor, I confess to watching Flirty Dancing ..... I'm fascinated and smitten with the premise!)
I'm a huge fan of the Turner Classic Movie Channel, love Classic Movies.
