elderly monitoring system
Like, OLD NAG old. Older than WKRP old. Not quite DINOS old. But old. Made this XER ugh, that "word" feel waaaay too young for this puzzle. Almost like a teen AGER ugh, that non word. The concept almost works, except for the DARNED answer see above, but it's all too cornball for me. The fill generally matches the theme, i. e. not from this century in any way shape or form. Grid is crowded with tired, old fill / crosswordese.
