It's nice to see reviews with some nice criticism with some valid point about the ride experience. It's something a bit different, compared to the universal praise It's been getting from enthusiasts as of recently, but I guess you gotta expect that with a new ride. It has lots of good bits, but a lot of not so good bits personally. My favourite bit was easily the trommel, it's a fantastic effect!! So simple, yet so effective. The 2nd biggest highlight for me is the mirror corridor (when it works), I love it!! Though the flash at the end feels a bit unnecessary, and you can see it when ot triggers by the car in front just before you enter the scene, but hey, that's a tiny criticism and doesn't affect the ride heavily whatsoever.
My 3nd favourite bit has to be, the new Ghoul that replaced the very last one in the screaming heads scene with the smoke exhaling out of of its mouth just before you enter the garden. It's a genuinely really cool prop and it was nice to see a prop that wasn't Emily or a doll for a change. It definitely fits that scene a lot more than the troll ever did, and that's coming from me, a huge fan of the original HH.
I'm still confused to why they thought the screen of Emily in the Grand Hall would be a good replacement, it kinda makes the mirrors feel very redundant, and the scene feels a bit empty personally. They could've just repainted the demon prop or replaced it with a new one with Emily or something to fit the rides Theme and it would've been a huge improvement personally. It wouldn't have been that hard to fix the mechanical arm for the prop, new or old. The company that made the original effect (aside from the prop of course) are still around, heck, they promote it on their website for their special effects page.
As a whole, the ride does seem to be in a work in progress so far, so hopefully the technical issues will be resolved this season. Some genuine really good effects in there, and there's some not so good ones.
