Except for the dance of the chimney sweeps, as a musical, it won't be memorable but it does have high quality set designs and other quality production values that make it worthwhile.
The writing was good & the screenplay compact. The early scene shot in a back alley of a wet Melbourne resulting in a dead cat was a good way to establish the relationship between the 2 lead characters. Crowe is good in this & Weaving as usual excellent.
It took a little while to come to grips with the screenplay and a second viewing will probably be an advantage – in any case, the performances made it worthwhile.
Whilst not as good as "Brazil" (1985) (my main negative was that Willis is not anywhere near the same class as the talented Jonathan Pryce) the writing & its execution is still visionary & as with the earlier film will not suffer from another viewing.
The screenplay was a bit of a mixture. You can't escape the feeling that partway through if it had have taken a different turn in the road it would have been much better. The ingredients were there including a capable supporting cast.
