The more I see of this ride the less I feel I can critise. It's true the capacity won't be great. Although I don't think it'll actually be quite as bad as we first feared. The transitions are snappy and it doesn't waste time with a slow lift hill. Chessington as a park also has a fairly low capacity, so based on the daily guest cap I'm not expecting any worse queues than something like The Smiler gets at Alton.
And if we look past capacity I really can't fault the ride. It's fast, has interesting elements, really unique compared to other family offerings and has that B&M quality.
From off ride It's also an incredible spectacle. It's going to be amazing stood in that area with those wide winged trains surrounding you. And it's a proper area; Main ride, 2 support rides and F&B facilities. With some good themeing thrown in as well.
When you compare this to Zufari and previous large investments it really is a massive step up.
