Record Weekend of Premier League goals...Good or Bad?

Must admit I'm a huge fan of high scoring games, its really good on the eye but is there as much bad as good of this? This past weekend there were many high scoring games and pretty exciting ones but did this record weekend highlight the quality of attack in the EPL or the lack of defense from various teams. In most games I watched or saw the highlights for there were many set piece goals as if they teams have forgotten how to defend them. Once again Arsenal struggled from them (poor referee I might add) Man United, Sunderland, Aston Villa...it is an alarming trend..
