well, first of all, this was a very nicely animated movie, with good visuals, quick and nicely organised animation, cool face expressions/fast paced scenes, and a good layout/design overall.
however, i do find your story to be... stale, and without any good punchlines.
i mean, i get it; the protagonist is the pretentious guy who ''pretends to like old music'' in order to be a part of an ''older era'' and in order to belong in a state of ''musical elitism'' , and i've met some of those teenagers/kids that like ''old stuff'' and that they feel that ''they dont belong in this generation.''
however, unlike your views, this does happen.
there are people who feel better at listening music from other time periods, and not just because ''they want to fit it'' or to ''look cool''.
while there are morons who are pretentious when it comes to music, those people are a minority when it comes to music lovers, and the large majority of (young) people who like old music, is because its (alot) better than modern music.
ofcourse, im not saying that ALL of today's music is bad...
there are many good songs, and there are many good artists today, that create beautiful songs, and nice music.
but, if we compare them to the legends of older times, their shine fades a bit.
also, if we compare the good music/bad music ratio of today (an estimate of 30%/70%) and the good music/bad music of older times (esp. in the 60's, 70's, 80's), (an estimate of 85%/15%), then we can all see that things are bad, music-wise.
nowadays, we have the technology to record the sound in perfect quality, and to remix music in millions of ways, thus making the job of new musicians alot easier than it was in the past.
but (some) people in music today are people without talent, without inspiration, and without anything to move them forward, into new paths in music.
i like (almost) all music genres, and i can appreciate any good music track, no matter if its rap, pop, folk or country songs, i like good music, if its nice & well orchestrated.
so yes, good taste can exist on anyone, and as long as the music's good, its worth listening to/worth the praise.
however, your movie seems to be ''one-sided'', and aimed towards everyone who happens to like ''old music/old stuff''.
infact, you've transformed a pretentious teenager into a gerontophiliac, and you've depicted him going in such extremes as ''desiring old people'' (since he slept with the sick dude in order to get old), and you've depicted him ''wishing to become old'', which is simply insane.
ofcourse, exaggeration is sometimes a good element of comedy, but in your movie everything was one-sided, pointless and without any cathartic feeling of joy, not even with a piece of crazy shenanigans.... (unless we count the ''im dying of old age?'' ''no, you're dying of olf AIDs!'' , which was good for a chuckle, but it was a small victory after a boring & unfunny movie).
in your case, exaggeration didnt worked well, and some moments of the movie were strange.
i mean, why did those old guys in the concert beat him up?
was it because he ''tried to fit in''? was it because they felt insulted by this kid's pretentiousness?
and even then, was that necessary to be shown in such a way?
(heck, you could even show him talking to an old musician, and he could be saying ''but, my child, you werent born when those stuff happened!'' and then, the pretentious kid would be sad, but the viewers would learn a valuable lesson. you could even add a scene showing the kid learning from his mistakes, and to start liking music for what it is; beautiful sound. and he would become a person that would appreciate music not because of stupidity/pride, but because of personal taste.)
instead, your movie was a thing that felt empty and unfunny, and thats sad, because you have the talent to create good animations, since your drawings+your animation is excellent.
you have to improve your storytelling/your stories/to add humour in your movies. (instead of adding a ''shocking/vulgar'' display of goofiness disguised as ''humour''.
last but not least, you should NOT add your personal opinion about people who think that ''they belong in the wrong generation'', but you should be making a cool movie, with good jokes, a beginning, a middle and an ending, and with some moral to teach people when the movie ends.
i know you can do it, you have the artistic skills in visuals, so it will be (fairly) easy for you to add a good story in it next time.
oh, and filthy frank is a very good comedian, who exaggerates about situations in a politically incorrect way (which is so refreshing), and thus, he is proving a point.
in his ''im in the wrong generation'' video, he's saying that: ''WHO CARES? JUST LISTEN TO MUSIC, you MORONS!'', so yes, thats a good message:
''stop being pretentious, and just listen to music that you like.''
thats the best message that one can deliver in his movie, regarding this ''issue''.
and he uses exaggeration in a clever way, in order to help deliver his message across.
you shouldnt call him unfunny, until you manage to create something that's genuinely funny. and even then, you will be just rude if you do so.
also, judging by your author's comments, and by the constant use of the F-word, (such as in ''Enjoy I guess whatever F you''), i can assume that you are an ''internet-badass'', and/or a pretentious douchebag, which doesnt make you very different than the people that you are mocking in this movie. (even tho, i honestly hope to be wrong; in that case, i do apologise).
stop being rude, try to animate funny+stuff that you enjoy animating (with the constant presence of quality+humour(or good storytelling) ), and stop splitting hairs.
just have fun and create cool stuff.
all this ''musical elitism'' doesnt exist (at least to the extend that you make it look like), and your attempts to fight it are not funny.
focus elsewhere.
be cool.
thats all, if i tired you, im sorry, i just tried to provide some helpful feedback, that is all.
4,5 stars for the visuals, no stars for the complete lack of humour. (and due to the general unfunny-ness)
