Have been pretty pessimistic with Ghost Train up until now...
Went on twice today, thoroughly enjoyed both. However, during the preshow on our first run, the lighting experienced an error resulting in Derren having no legs and being almost completely transparent, also, on the same run, the train in the safe room didn't move towards us whatsoever, resulting in the actors hilariously/awakardly jumping out of the way of nothing, but luckily an infected actor enhanced the experience.
Fortunately, the VR made up for all those errors, it seemed like all the 4D effects were working, everything was in sync, I received different characters and the dialogue felt a lot longer compared to the technical rehearsal run. Second segment was still meh, however the quality seemed a bit better compared to my last run. Happy to say I went from a 4/10 to a 7/10 today (also, didn't break down once/experienced major problems today).
