Melodic death has always been an extremely hit-or-miss style to me. While saying I despise most of it would be a bit overboard, anything less than excellent in that style is extremely hard for me to listen to. There are a number of bands I can really enjoy for the fact that all the pieces seem to fall together perfectly, or close to perfectly (Dark Tranquillity, Insomnium, Depresy, Garden of Shadows, Eucharist, Arsis, etc.). When a melodeath band fails to do that, it just becomes so incredibly tedious and unlistenable for whatever reason. Brutal death is different. There's a handful of acts who rise above the rest, but unlike melodeath, it's not something you can mess up as easily, and I'll still be able to listen to (and enjoy, to one extent or another ) a mediocre brutal death band.
