Basically the In Flames elements are still the same.
If you want to listen to (melodic) death metal, listen to their side projects (Dimension Zero / Sacrilege). Very good stuff. But there is definately something within In Flames which makes me listen to them. In Flames has never stopped producing fine melodies, finer than a lot other bands, but that depends which type of melody you prefer. They just changed the sound around. I can listen to Moonshield, and I can listen to Alias, and say, yes that's In Flames.
And, nobody tells you to like it. But I'd really like to use the word "changed" instead of "fallen"
