Broken Base: When they changed their sound with their 2002 release Reroute to Remain, many longtime fans who had been following the band since they first emerged reacted negatively to their change in style, citing it as 'not being heavy enough', and describing Anders' clean singing as pussy. However, some fans loved the new sound, at times even more than the old. This conflict has led to many internet wars, particularly on heavy metal websites and on YouTube videos.
Crazy Awesome: The band is notable for including folk music elements in their early music, and as being one of the first bands to do so. When people heard about this, they thought that it was a stupid idea, since metal and folk are like rap and classical when it comes to similarities. Why exactly does this situation fit this trope, you ask? NOBODY SUSPECTED IT WAS ACTUALLY GOING TO SOUND GOOD, AND IT DID. In Flames pioneered a subgenre of heavy metal nobody thought could be pulled off.
Epic Riff: Stand Ablaze, Moonshield, December Flower.
Behind Space. That is all. For an old In Flames fan (like, who met them with Lunar Strain) this is THE Epic Riff from them.
