It was a honest mistake

I don't know if TV in the USA is snowed under by "reality" shows, but over here it seems to be.
The other day Sam was telling me about the new series of "Prison Break", how good it was, and had I seen it. (She works lots of evenings, so doesn't know what I watch on TV.)
I told her I wasn't into reality shows, as they bored me to tears. She then explained that "Prison Break" is NOT reality TV, but a serial.
Whoops!

Why did I think it was a reality show? I think because it appeared when there were lots of others appearing, like a rash. And there was something about a challenge, about people "escaping" from prison, and to see how far away they got within a set time. It may have just been a local thing run by the Rotary or Round Table, to fund raise, but this had got lodged in my mind, so when I saw "Prison Break" advertised, I just presumed that was something similar.
Am I missing something really good, or should I carry on, watching very little TV?
