The sense of theatre that Vampire has/had was always the best part... The second half especially with diving towards and over the main pathway is such a simple piece of ride theatre but is one of the most iconic Chessington images...
Certainly in the grand scheme of things, it's been evolved past, but comparing to other Arrow suspendeds, it's probably the best that still exists after the closure of Big Bad Wolf (which was Vamps on a larger scale essentially, but that finale was insane), and Eagle Fortress...
Vampire was also my first coaster, so it does hold some nostalgia there as well... Yeah it's been butchered a bit, and unlikely to go back to the original days, but it still has the same sense of theatre and adventure for the target audience... Kids love the thing, and that's the important part...
