It was certainly broken when I went on 28th July. It was disappointing; that effect was possibly one of the strongest in the ride for me, and definitely the strongest reused effect!
On that note, my ride on the aforementioned visit was only my second ever go on Alton Manor, with my first being only the week after it opened in March 2023. My thoughts remain quite similar to when I first did it; it's a nicely done refurbishment of Duel overall. It has some absolutely excellent set design, with some of the new sets being wonderfully detailed and surprisingly big and the reused sets working well within the new theme. It's got a nice, cohesive storyline. Some of the new effects are really cool additions and executed well, with the ending and the mirror scene being particularly cool ones for me, and I also think that projection mapping is used to great effect in parts of the ride and works very well. Furthermore, I also liked some of the new additions compared to my last ride, particularly the enhanced hide and seek scene.
With that being said, I do not think the ride is perfect. I think the screaming heads scene still doesn't work very well in this iteration of the ride, and I also think that some of the later added (post-opening) screen and projection mapping stuff doesn't work that well. I'm mainly thinking of the random projected skull on the wall before the screaming heads and the projection of Emily popping out of the coffin in the hearse; I'm not personally a fan of either of these effects, and I don't think the ride would lose anything without them. With the projected skull in particular, I'm convinced that's just some generic royalty free video, as Great Yarmouth Pleasure Beach had exactly the same projection in their Haunted Hotel ghost train 2 weeks later...
It's not an absolute personal favourite of mine, as I'm not the world's greatest horror fan (Duel wasn't either), and I do perhaps not rate the ride as highly as some. Nonetheless, I enjoyed my ride on Alton Manor and I think it's been a successful revamp overall.
