There are just too many to name so I'll just pick a few and speak briefly.

Popular music in general (not universally as there are a few exceptions in today's popular music that I find to be quality like 'The Killers').

Revival and excessive consumption of teen to early twenties dramas and their invasion in to nearly every genre of television while quality shows that actually kick ass continue to get canned early. The public listens so much to popular trend where television is concerned that absolute crap stays on the air for years and shows that are awesomely written and performed are lucky to make it all the way through a whole season because they don't cave to peer pressure. I swear to god why the hell do they revive shows like 90210 and Melrose Place and continue renewing all the crappy evening soap operas like them. Why can't they let shows that are well done stay on the air instead?!!!!

Lack of originality in Hollywood. I like a good sequel as much as the next guy but so few of them (at best 1 or 2 a year) are any good. Almost everything that comes out as a major release these days is a remake or a rehash or a sequel of things that have come before.

Hollywood continuing to convert crappy books into 'blockbuster' movies while a vast array of awesome literature across all genres continues to go untapped! Oh, and the butcherization of the few movies they do make from quality literary sources; where they take so much 'creative license' that it has almost no resemblance to the original work beyond a title and a few character names.

The continuation of the general trend in videogames of graphics over quality. Yes, I agree good graphics can be a vital component in improving the quality of a game but far too many games consider nothing but graphics leaving piss poor gameplay mechanics and story in place and untouched just because the designers are content with how pretty or shiny the graphics are turning out.

The vast influx of sequels to crap games while awesome games go forgotten and unremembered. Why can't we get sequels to awesomeness like Beyond Good and Evil, Psychonauts, and my personal favorite action/adventure game of all time 'Shadows of the Colossus'?? Instead we keep getting crappy shooter sequel after crappy shooter sequel.
