To clarify, allow me to provide a definition from the fanboy dictionary revised edition.
bandwagonageddon - n - the utter destruction of something good due to bad ideas being blindly followed
Example: The Flash is good. We like Him. Wally West is a neat character who long time readers have watched grow up and become a great hero. Bad idea of bringing back Wally's long dead mentor and predecessor, Barry Allen is introduced. The company goes with it, because even though they know bringing this character back from the dead is the stupidest thing they good possibly do, they do it anyways due to nostalgia. People read it, and somehow ignore the stupid because of some sort of memetic trickery.
Its like the idea of something carries more weight than the actual thing. Things are thought of as great, but really they kind of suck, but various factors cause us to overlook the suckage. And this is why we're all doomed.
We can't just go along with this crap! We have to go in and intelligently determine why ultimately Blackest Night was dumb, or why Scott Pilgrim is a tool. Sure there will be die hard fans who don't understand how you have a problem with The Dark Knight and think your dislike of it is some sort of horrible character flaw. You can't convert them. They are lost. Empty vessels waiting to be told what the next thing is that they are supposed to worship, love and throw money at.
But then there are those whose minds can be sparked. They don't care about Tiger Woods. Why don't think the Government should be doing all the crap they're doing despite them claiming they know what they're doing. They've got a few legitimate doubts about the Pop-Star-in-Chief. They see what's popular and are wondering what all the fuss is about.
Don't follow the shepherd. Be the shepherd.
If no one is willing to lead the charge upward, we all fall downward.
Now get off your ass and do something amazing.
