Logic FTW!
How in the world are we supposed to individually discern who's bandwagoning or not? It's nearly impossible. Any positive/negative influx of any given product is due to the fluctuating users that are on. There are never the same group of people for any given time, especially in such a big place as the net.
This whole Spidey reboot thing is a perfect example. If you see a rise in Raimi bashers, why would you assume these are composed of the same people that praised the man years ago? Unless you were some sort of stalker that had remarkable memory, it's highly doubtful you're even talking about the same people. It's not unfounded that new users come on here with certain preferences that might favor the current trend. It may not even be a case of them necessarily following a trend, it just coincides with it.
Case in point, I truly believe Wolverine Origins and SM3 sucked tremendous amounts of balls. It has nothing to do with them being fanboy piñatas. Imo, they are one of the lowest forms of comic book cinema. Honestly. I laugh at anyone that actually tries and explain away my perception of that. It's adorable how ******** people get.
Bandwagoning exsts. It can't be stopped, it can't be tracked, it's rarely proven. Deal with it. Worry about your own opinions.
