"Personally what I love about it is that it know exactly what it is and knows not to outstay its welcome. It's a slight concept at best and atm it is short, sharp and tight af and leaves the audience wanting more which is the perfect way to create return customers and a massive buzz which is what it is doing. The audience leaves the theatre on a total high because it all just works so perfectly.
It is what it is and it is working. To risk losing what is so good about by changing it it isn't worth it imo."
Yank here who saw this last week in London; for whatever it's worth, I agree with this completely. It works perfectly as it is; "fleshing it out" to satisfy some pre-conceived notions of what a musical needs to be really risks breaking it.
