Over the years, Halloween Haunt has become a place where it is more family friendly or perhaps the age group is generally more high school students than not. After it reaches to about 8-9 pm, the lines and place becomes extremely crowded. Long lineups and to make things worse - they don't properly space you out so you end up just walking through the attraction without being scared at all.
Would recommend to create some gap in general rather than sending a huge group at a time only to catch up to the next group in the attraction and just be in a cluster.
Some of the shows were nice to see - Sin Lounge demonstrated a spectacular performance with pole dancing, acrobatics, and a minor fire show. Very good in that sense.
