Exactly. It's a piss-poor ugly-ass replacement for a location we spent three whole seasons in. The fact that Twilight's library was unceremoniously blown up and replaced by that eyesore is bullshit. Not to mention the fact that crystals are Cadence's thing. Were the writers really so lazy that they couldn't think up a new theme for Twilight's new castle. Plus there was that plot thread regarding the Castle of the Royal Pony Sisters in the Everfree Forest. Why the hell did they spend so much time claiming they were going to fix it up and not actually fix up the damn castle? Even in it's ruined state it's still way more elegant than that crystal monstrosity. But then Hasbro would have to figure out how to make it into a playset, which was clearly the Crystal Clusterfuck's only reason to exist.
