Idr the name of the effect -when you notice something and now it's on your radar so it stands out and it's more glaring when you notice it again, until you start seeing it all over the place...

Unwarranted hate on Frankenstein's monster. I feel compelled to defend the duder every time I see it pop up, and lately I keep seeing it pop up.

Obligatory plug: if anyone reading this hasn't read Mary Shelley’s original story, consider giving it a whirl. It's old-ish English, but not like Shakespearean or anything - it stops looking/feeling 'old' after the first chapter or so. It still holds up to modern standards, and is the original sci-fi horror. The monster in particular is an actual character with its own personality and arcs - not just the mindless zombie portrayed in media since.
