The 3D talk has me thinking back to all of the 3-D HHN houses I've experienced. IMO, the majority were sub-par to awful. However, I really did enjoy The In-Between in 2011. Jack's Funhouse (2007) and Alice in Wonderland (2015) were both decent. The others were really bad. I think a 3-D house once every 3-4 years would suffice.
