As a modern anime with professional production values it looks and sounds good. The voice acting is excellent and the colours are used effectively to create a great looking anime.
The real problem for me is how the anime is so unbelievably biased in how it looks at Britain's societal structure in the late 1800s. It's such a partisan view that, as someone who has studied that period extensively, it's almost impossible to ignore. For one it acts like Britain's class system was highly stratified so that only the nobility could ever really get ahead, this is false. Modern Britain is arguably more stratified than Britain in the 1860s and escaping poverty is significantly harder now than it was then for a large number of reasons that principally come down to the demand for industrial labour. The show also focuses on classism but ignores the fact that in Britain the upper class and the lower class have generally always had good relations with one another. The people in Britain who had extremely poor relations with the upper and lower class in Britain were the middle class. The idea of the sneering upper class spitting down upon the starving lower class simply wasn't a thing in Britain in the 1860s and it's a key part of why those aristocrats delivered massive majorities to the Liberal Party throughout the 1860s.
If you can stomach the bad history you might like it though.
