Managed to get on it twice today as it was open for technical rehearsals again.
Compared to Fridays ride, it was a lot better. The 4D effects seemed a lot stronger and prominent and the experience seemed to flow a lot more.
It does still need improvements. I find the VR to be blurry no matter how I focus it, and the headphones just aren't loud enough (While the VR shows an empty train, I hear people screaming around me).
It is a very good attraction and one that I'm glad Thorpe have decided to put it in other than another rollercoaster. It is without a doubt the best dark ride in the UK.
A good 8/10 from me.
