2013: Afterlife - Read all the stuff about IB and PT and had it in my thoughts this wouldn't be bad for my first year. It was lame, a "throw all the cool effects we got" 3D house instead of any attempt to put anything together.
2014: Roanoke - Not scary, and sets were generic. A tour of Roanoke. Finale surprise wasn't really worth the hype. TWD avoids this because I didn't go in 2013's so it was a newish experience for me (*Cough* 2013 Zones *Cough*)
2015: RUN - Scareless on all runs. Things come and go too fast to make sense. Lots of the same transition room. Meh. Purge and TWD had decent scares at minimum over this.
2016: LP3D - What zombieman said basically. My least favorite HHN house. Icon having a 3D house should ever be an idea again. Once again, 3D for the sake of throwing in effects and stuff instead of trying to tie together.
2017: The Shining - Horrid queue line for a honestly more boring house than anything. Sets feel grand enough. Scares happen, but they don't hit, exception of Gold Room. The abstract stuff was inconsistent with the real stuff, unlike Exorcist where they at least stuck with the artsy stuff the whole time, and the non-artsy stuff connected better in my opinion. Still not in my bottom 5 though.
AWIL 2015 (Night and Day on this one between two houses.)
La Llorona (Lots of ladies reaching out of the dark. The 2nd half was basically incomphrensible.)
