Well as others have said, dark ride are always hard to judge from POV videos, so I will reserve my full, 100% judgement until I've seen it in the flesh.
However, as a massive lover of Wallace & Gromit I can't help but feel that they've rather missed a golden opportunity with this one. It looks as if Pleasure Beach's design team have sat down with a DVD boxset, watched through it, and said "That can be a scene" every now and then. It seems very willy nilly, and there appears to be little or no continuity and story to the ride, which is a shame as the name, vehicles, and frontage would all suggest a unique storytelling attraction (To me at any rate).
I would have expected it to follow the basic W&G premise while doing something new and different to the existing stories. Wallace invents machine, invites the guests to come and try it, it's all very crazy and kooky, something goes wrong, comedic actiony scenes progressing the story, the final confrontation, all is fixed, happy ending, and a packet of crackers
Instead it's more inline with what I might call a "studio tour ride", where you're simply shown a collection of scenes from the film(s) (I.E. Hollywood Tour - Phantasialand).
Whilst the scenes are small I wouldn't shoot the ride down for that. I do love huge, grand dark ride scenes, such as the garden in Duel, and the finale of Silbermine at Phantasialand, but when you have limited funds and space it's not unreasonable to have smaller scenes. However, what scenes there are here feel very basic and uninspired. They all feel very static and simplistic in their animation. There's nothing wrong with just having simple animatronics, especially when you're on a tight budget, but I personally feel that if you're going for the simple style you should compensate with more of it.
Rides like Carnival Festival at Efteling are simple and basic in their appearance, but because virtually everything is animated to make up for it you're so busy looking at everything going on you and trying to take it all in that don't really focus on one thing and say "Well that's robotic and low quality". They could have decked out the scenes a little more to make them feel more creative, rather than having just one or two moving objects I feel.
So yes, from the POVs seen that's what I would say about the ride so far. Not totally dreadful, and no doubt it will have its place at Pleasure Beach, but a very under-utilised brand and a rather uninspired dark ride. However, as I said, I'll cut it some slack until riding in person (Though I'm not really holding out for much).
