I can't really rate the houses numerically this year because they are all so different. Here are my quick impressions, based on 14 nights so far this year:
The soundstages (Wolfie, Frank, and Drac): If I had to rank them, Frank would be my favorite, followed by Wolfie and Drac, but Wolfie is almost tied for number 1. Only problem with that one is some parts are scene based, and if you miss the scenes it is much less impressive. I got one of my biggest scares of the year in there tho'. In Frank, I like to see my hubby getting attacked...a pleasant change from the attacks being on me. Drac is consistent...lots of jump scares from the brides. And of course the scenery in all the soundstages is great. I like the gypsy camp in Wolfie and wish they had scareactors out in front of the other two.
Cleaver: The first time through I hated it because I had totally different expectations. Once I adjusted that, it soared to the top of my list. I just love the dark humor (and watching people get lost in the chainsaw area). It's so hard to describe this one; it's sort of a "love it or hate it" house. I think it will be the one I miss most when this year is over.
Saw: Great house, but very scene-based so if your timing is off, you will exit thinking, "What was that supposed to be?" I love it...those pigs are downright creepy, and they do a great re-creation of the trips. It's just a pain having to get there early because the line gets insane, so we usually hit it two or three times early on.
Silver Screams: The most under-rated house of the year. Universal didn't play up the Usher icon this year because of the three movie icons, so people tend to be clueless in this house. I really like it, especially the "behind the screen" scene. It rarely has a line, except on really busy nights, because people head right to Chucky.
Chucky: Speaking of Chucky, this is your typical "funhouse" haunted house, and I enjoy it because I like those types of houses. The entrance tunnel is wicked disorienting and there are some good jump scares, although the best ones are a matter of timing.
Spawning: I like the heavy strobe use at the end of this one (I literally got lost the first time through this year), and there are some good jump scares. It doesn't really have scenery changes because it's all in the sewer, so don't expect major production values like the soundstages.
I feel sorry for people who only get to go one or two nights because I think you get a totally different view of the event. My viewpoint always changes over the course of the year as I see the houses evolve and get to see more details.
