First of all, NO FUCKING WAY is Come Clarity better than Colony.
I have both - in fact, I have every In Flames album but Whoracle, Reroute 2 Recycled Crap, and Shortcut to your Empty Trashcan, and this is NOT better than Colony... Colony is probably my favorite In Flames album, and although Jester Race was very good, it was a little too mellow for me.
That aside, Come Clarity is not entirely "mallcore" shit, but half the cd IS. Track numbers (I'm not writing the names) 2, 5, 7, 10 (check out the Jonathan Davis chorus), 11, and 13 - the closer, all suck in one way or another. 1 and 6 are borderline at best. Really this cd is nothing special at all. (Scream is one of the worst songs I've heard in a long time, by the way)
That being said, it is better than the last two, but still doesn't touch thier first bits. And, I did actually buy the cd. I don't regret the purchase, because the rest of the songs are good, but certainly not "epic". If you want "epic" Gothenburg, check out Dark Tranquillity or At The Gates, two credibly good bands.
