I know almost everybody will have an answer for this one, but there's one fanbase I just cannot stand: Rhapsody, or as they're known as now Rhapsody of Fire. It's kind of a long story.
Fans of Rhapsody have always oversold how great the band is and part of this is the band's fault. If you've ever read a Rhapsody press release (see below) it definitely overhypes what the band has accomplished:
Rhapsody have been a unique phenomenon in the metal scene since 1997. Metal fans all over the world welcomed the band's debut album, "Legendary Tales" with astounding enthusiasm. Together with Hammerfall the band advanced almost overnight to become leaders of a new generation of future-oriented metal bands. "Legendary Tales" was followed two years later by their second opus, "Symphony Of Enchanted Lands", which climbed to 54th in the national album charts. In Finland it reached 41st, in Italy 22nd and Holland even 14th. The voices of the international press were especially loud: The German metal magazine, 'Heavy, oder was!?', the Dutch 'Aardschok' and the Belgian magazine, 'Mindview' named "Symphony Of Enchanted Lands" Album of the Month. Rhapsody was featured on the cover of numerous magazines in France, Norway, Greece, Romania and Italy. The extensive European tour with Stratovarius from early April until the end of May 2000 was the stage premiere which had been! so longed for by the many fans. It was followed by the third full-length album, "Dawn Of Victory". The album was even more successful than its predecessor and reached high chart positions in numerous countries. In Germany, "Dawn Of Victory" reached 32nd place in the album charts, in Italy, Finland, Sweden and Finland the album climbed to similarly high positions. In Japan it reached 24th and in the Dutch Indie-Charts it reached a staggering 4th.
Early Summer 2001 saw the band touring South America for the first time, leaving ecstatic fans behind them not only there but at various Europan open-air festivals, too. Now the musicians are presenting their first specially priced album, "Rain Of A Thousand Flames" in preparation for the thematic finale of the successful 'Emerald Sword saga', which will be appearing at the end of February 2002 in the form of a full-length album.
Unfortunately, things became complicated when Luca Turilli, a key member of the duo that fueled the band, left. With two bands instead of one I thought Turilli was in a good position to produce the better output since his previous solo albums were so strong.
That's not how it turned out.
In my opinion both bands have struggled to put out anything as strong when the two hales were one. Turiili's latest album (under Luca Turilli's Rhapsody) had two good songs but the rest I passed on. Rhapsody's (er, Rhapsody of Fire's) latest launched with a single that sounded insanely rehashed.
The the reason I state the above is when the band splintered the fanbase splintered and it has become even more insufferable. People who once praised everything Turilli did with Rhapsody say he completely sucks now and fans of Turilli say Rhapsody of Fire sucks.
As for someone like me who thinks both sides have suffered tremendously and trying to be more objective about it? Yeah, there's no place for me, screw me for trying to mediate some common ground.
Runner up when it comes to music would be Symphony X fans. I like some of Symphony X's music, but when I try to tell fans i don't like it all and I don't care for the band's twenty minute opuses? Yeah, that goes over well.
What fanbases do you dislike? Can anyone think of any that have become splintered like the one I talked about above?
