this has nothing to do with it being too "mainstream", it's just that this video is absolute garbage and anyone who isn't blind can clearly see this. the first 3 were funny but then the quality just started decreasing drastically.
If it's garbage, then shouldn't anyone with a computer just be able to open MS Paint and make one themselves? No, making garbage
obviously takes weeks to do and an entire team of people to complete.
Don't diss it just because it's not your type of humor. There are many people (myself included) who enjoyed it a lot. There is most likely humor you find hilarious that I wouldn't even crack a grin at. But I'm not going to say bad things about it; I know somebody enjoys it, which is good enough for me. asdfmovies were all meant to be random, unexpected, and spontaneous. I'm pretty sure that humor is still there (they even refresh some of the old jokes, keeping them going). If you don't like it, either move on, find humor that fits your fancy, or make your own.
