Metalcore is the same as every genre: it has its ups and downs. Whenever a genre becomes more "fashionable" a lot of mediocre music comes out of it (see 80s hair metal) and core is just going through this phase now. This means that people who want to feel superior about their taste will actively bash it just because the kids are loving it at the moment (I was no different like 4-5 years ago). I totally dig Converge, Coalesce, Poison the Well, Zao, Architects, ABR etc etc. Core pits are also the fucking best.
