Fully agreed, while I did love Merlin Woods, there's no doubt in my mind that it truly was a necessary sacrifice considering the state of the parks at the time. Because without Potter which led to the purchase by Comcast*, I truly don't think the parks would be where they are right now.
* = A while back, I remember there was a thread of Comcasts acquisition, and that was a very unique time capsule as a lot of folks had a very negative reaction to the news. Little did we know at the time, that would be one of the best things to happen for the parks.
