I just read it myself and after praising the article they ran yesterday about doing a pretty good job of summing up both sides, this article was the exact opposite.
They also say Flight of the Hippogriff and Dragon Challenge conversions "is in no way different" from the Maelstrom conversion due to a change in queues?!?!? I'm sorry but that statement is just way off the mark from anything. If he really wanted to do a comparison of HP to Frozen, the closest would be Hogwarts taking over half of Lost Continent.
