Well done edgy humor always has its place. Its always sunny is plenty edgy, moreso than anything mainstream from any time prior, and extremely popular. The problem with people who make those comments is they could have NEVER made anything good, theyre uncreative and unthinking, and so they get locked into an outdated mentality and their humor never develops past whatever they found funny in their formative years. Because some things are edgy AND good they mistake being edgy for automatically being good.
