This isn't representative of Warcraft?

You are just trying to handwave criticism away with blatantly false statements. Yes HS has always been goofy. But the goofy things were boss dialouges and flavor texts.
In Kharazhan you have two encounters fighting silverware and a magic mirror. The cutlery and the Khara-khazam card being obviously inspired by Beauty and the beast from disney. While the magic mirror is obviously from snow white. Furthermore Kharazhan is already an established place, with its own raid. It never had animated cutlery or a magic mirror to fight. With Loe atleast Blizzard created something new. Kharazhan was a fan favorite raid. Why shouldn't people be upset when you are fighting silverware instead of an actual boss? Especially since previous adventures were made as wow raids. Not a silly (stupid) event. Why would Medivh invite everyone to a party even? It's just retarded.
The card art of some cards also doesn't match the warcraft style. For example the fork card or khara-khazam. Medivh art looks like he is the protagonist from a Disney movie instead of the Warcraft Medivh. Bookwyrm, babbling book, wicked witchdoctor also look very un-warcraftish. And no it wasn't always like that, and the visual design is one of the things which made Warcraft great to begin with.
