@SleepingSilenceJust because something is harder to produce and takes more time doesn't mean it's better than something. People put a lot of energy and focus into creating a song that only very few people like. Those few people consider the incredibly underground group talented because of the song they made. Is noise music as hard to make as one of your Hollywood Undead songs? Eeeeh. Wouldn't say so. But fans of that genre consider the creation of that music to be the apex of quality, and Hollywood Undead to be particularly terrible because it just sounds bad to them. Some people find true talent in simplicity, and some in complexity. Once again, no individual(s) can really determine, objectively, what is better in regards to artwork. We are too divided.
Do you like Nicki Minaj? Some think that she's far more talented than the Hollywood Dead and that her music is much more detailed.
Finnegans Wake, a book by James Joyce, is one of the most difficult books to read in English literature. He utilizes (I think) 20 different languages from across the globe and then adds a colloquial twang to nearly every single word. I tried listening to the audiobook. It's a horror to try and comprehend.
But then there's a split. It took him 17 years just to write this book. He put nearly two decades of work into writing this piece.
Is James Joyce talented? Even English professors think it's just gibberish and unnecessary. But then that same group believes that . . . I don't know . . . the first book of Harry Potter, which only took around five years, is far better because it appeals to a large group, the writing is concise and understandable, the plot and characters are very good, and the setting is solid.
And then you have avant-garde music. John Cage's 4'33". You know how much work he put into "composing" that?
Guess:
https://www.youtube.com/watch?v=JTEFKFiXSx4He is regarded as a 'talented' artist. Is he talented? You decide -- but for yourself, of course.
I'm just going back to the point that even though us humans have created an innumerable amount of artwork over time, are not at all fit to set an objective standard for what is truly quality, or set a benchmark standard.
I actually don't like this idea myself because I do find myself agreeing with you that Citizen Kane is much better than Sharknado, but that's just our own opinion.
(alright im done ranting like an ass now)
tl;dr
it's pretty much all subjective
