The effect of the distorted van as riders go whizzing past looks amazing, but the overall ride area lacks any impact and to me, still looks ridiculously undone. That outdoor queue fencing in particular is a bit of an eyesore. That said, I am withholding my full judgement for opening day.
The theming looks good, but I do hope that it's only going that slow because it's still in testing. The Smiler really struggled to complete a circuit during it's testing phase (some might say it still does but that's for another topic)
Once the wheels have ran themselves in and the train is fully loaded I'm sure it'll pick up some more speed through that final inversion.
I think you will find that's it is TPW rather than TPR haha, I'm very glad that they have got the subway - hole* - properly working with strobes and mist as seen on this POV - http://youtu.be/4qsax1e-c3c
