While I appreciate that the episodes of Ninja Warrior shown on Challenge are probably edited for timing reasons, I think the same needs to apply to Ninja Warrior UK.
Also a lot of emphasis is put on the need for speed, so to speak, on the original Sasuke programme as they have really tight time limits for everything, which doesn't appear to be applying here (or if there is a time limit I haven't heard it) so I think it's not really in the spirit of Sasuke to take the first obstacle at the speed of a snail...
