The obligatory romance sub-plot in everything shits me to no end.
Agreed. Very few shows do it well. But most of the time it just leads to Flanderization, another trope I despise.
-Hollywood pudgy is another one that ticks me off. 99% of the time, the actresses they say are getting fat are completely average weight. Way to encourage females with body issues.
-Glurge can go to hell. I get enough of that with religion, I don't need it plauging entertainment.
-"Not so different" can be done well, but there are times when it just comes across as preachy, trying to paint every day humans as no different from the worst monsters in history (another reason I despise religion).
-Last but not least, all of the "true art" tropes.
