I think The Blacklist is mildly entertaining garbage. I like Spader (sometimes) and it kept me interested enough for 1 season, but I tuned in for the first episode this year and asked myself "why I'm I watching this crap?" and turned it off.
I would rather watch a show completely based in fantasy, something like Sleepy Hollow (which deals with demons, witches, curses, pacts with Satan, etc), than to watch a "pretending to be reality show" like The Blacklist or Criminal Minds or any of the terrible shows based around letters; CSI, NCIS, etc.
Sleepy Hollow is a silly show, but it's an intentionally silly show, a knowing nudge-nudge-wink-wink kind of affair. That I'm fine with. Buffy The Vampire Slayer was probably the perfect version of that, a show about vampires/witches/demons that wasn't really about those things at all, just metaphors for the hell that was high school. In the series the writer literally put the entrance to hell underneath the high school.
When I'm in the mood for an intelligent, realistic series I'll watch something British. If I want fast-food entertainment I'll watch American TV.
