Honestly think it's really good, for what they have done in a short space of time brilliant. It's Alton towers the ride
Glad you enjoyed it!! Personally, It doesn't have any character or charm in it apart from the refreshed Gloomy Woods. When I heard John Wardley was involved, I was actually really excited, thinking we could see many aspects of the ride return to their former glory, and not in a technical manner, rather in style, but what we got was anything but. Definitely not for the family audience they're trying to bring in IMO. Way too dark and the concept is very uncreative, that and they stripped out the best parts of the ride, the original props! They replaced them all for either oversized dolls or Emily herself, making the ride feel very generic and no longer unique.
The lighting and audio is good and all, but (controversial) at first I thought it was better than Duel, but the more I think about it, the more I prefer Duel (when it was all working and lit well, and without the blasters.). Duel was spooky, but never took itself that serious and had a lot of charm, same for The Original Haunted House thanks to the props and lack of projections and screens, but for some reason, every new ride by merlin has to be the most grim and serious ride the can come up with.
There's been more reviews of it by families saying its way too scary and dark (story-wise) for their kids. It's scary, but it isn't fun if you get where im coming from. The original Haunted House had a scary factor, but even kids that weren't fond of being scared 24/7 could really enjoy it because it had a perfect balance of Humour and Scares. Lots of people have been praising the outdoor area, especially the outdoor queue because of the funny gravestones and amazing audio. It has a perfect balance, the audio is creepy, but the funny jokes on the gravestones are hilarious and anyone can have a good laugh with it.
The reason why the original Haunted House was very unpopular in the late 90s and early 2000s was because Tussauds removed all the humour away from it, so it just became a very generic ghost trains designed to only scare you. Imagine watching the same horror film over and over repeatedly that's heavily reliant on jumpscares, you'll get bored of it quickly and it'll just feel bland. This is why it was later concerted into Duel. I feel the decisions put in The Curse At Alton Manor has the same problem with the late 90s and early 2000s Haunted House but turned to 100 (generic topes of possessed child, creepy dolls, toys, etc.) and it will really badly effect it in the long term with it being too dark and grim with no humour or charm for the little ones, we'll see. Heck, it might only last 10 years, and I wouldn't be surprised personally.
If former members of Sparks and Rex Studios were also involved with The Curse At Alton Manor to keep the rides character with the new story, it might worked then. John only did the creepy aspect of the original ride. The props, the style, the humour element of it, the music, lighting, were done by different people.
The man who made most of the original props, Donald Owen, is still alive and makes props independently, same with Daniel Harvey, he helped with painting the original ride. He actually designed his own ghost train for Pleasure Island With his company, Studios East Ltd. It was named Shrieksville, and had a very similar style to the original Haunted House. It opened in 2010 and was considered by many as one of the best Dark Rides in the country until it was shut down along with the rest of the park in 2016. It was said to be very scary, but it also had humour like the original Haunted House had.
Oh, one more thing, the music in the ride can get a bit annoying and repeatative, each scene seems to use the same instruments and sound almost identical to one another.
