Popular is an understatement. It requires an absurd amount of work to see everything in this event and it was a Thursday (a holiday for some, but a weekday nonetheless) and I barely saw all the houses, and that was skipping Terror Tram.
I am personally frustrated about the clear overselling of express this year more than ever. I think that is exemplified by the fact that Five Nights at Freddy's was one of the shorter waits of the night, and it was posted at 180 minutes at one point. Every other house line I walked into was double the posted time and the express line never cleared. I had to wait 80 minutes for Scarecrow with a posted 30 and that was getting in line prior to 7:45 PM. I know the waits cannot be taken seriously, but they are supposed to be a rough guide. I did not even dare go for food once, hungry as I was later in the evening. While I am glad to see the event is popular, if a person on their own with a extremely high degree of experience at the event cannot see everything the event has to offer, that is a clear sign that there is a problem.
