Some thoughts on DBGT, having finally had the chance to ride it at the very end of the day a few weeks back.
First of all, I really like dark rides, and I really like most of this dark ride. I don't really think that it can be particularly faulted up until the half way point. The sense of anticipation in the pre-show was palatable, Derren's introduction is brilliant, and although it might be seen as too cerebral, the transition onto the floating train and into the tube car is brilliantly played and actually quite magical. This is the best stuff Merlin have done in years, up there with Disney and Universal in my opnion, or even Punchdrunk theatre productions.
The first train ride is really absorbing, and again, incredibly cool when the car suddenly 'accelerates'. Even though I knew what was coming, I was screaming and wincing as soon as that girl appeared at the window, as were my friends, and pretty much everyone else on board the carriage. The tension and suspense is racked up perfectly. Again, I don't think the designers are getting enough credit for this.
The train crash falls just on the right side of corny, and the actors/staff really sell it (at the moment.)
Unfortunately, I don't have much good to say about the return leg. I can totally see why the park opted for a 'go big or go home' ending, but it's frustrating in the opposite way to how the first leg is frightening and engaging. The demons ripping the side of the train off is a good moment, and the vista of the explosions is nice too. But the creatures getting up in your face is just silly, makes little cogent narrative sense, and is worse, repetitive. The graphics are woeful, and the 'gas' sequence when awaiting the next train to clear unloading is absolutely tedious. The fall into hell is completely unconvincing, and the final surprise is utterly predictable.
On the other hand, arriving back exactly where you started is a neat trick, one which nobody notices. The ride system for this must be amazing! A colleague was convinced we just got out of the train from a different door, went round the side, and got back in. He was totally oblivious to the complex system of three other vehicles, waltzing around each other. Which is both impressive, and unfortunate, given that the effect is lost on seemingly everyone.
I must admit, the ride is, if nothing else, completely unique to the world in terms of story, tone and system. In terms of technology, the park have obviously massively overreached, and I imagine there's a solid book to be written about what went wrong behind the scenes. Nonetheless, I did really enjoy it, despite it's shortcomings in storytelling. It's a noble effort.
