I went into this expecting not to like it; I figured it would be terribly worthy and earnest, and rather plodding and dull.
It's actually far better than that, and I found myself really enjoying it. I don't know too much about Queen Victoria beyond what most know - married to Albert, who died young, and she mourned him ever after. Seeing the circumstances she grew up under was fascinating; in fact I found myself wishing I'd seen more of the story, and I imagine we may see a sequel at some point.
Visually the film is stunning. The sets and costumes are incredibly lavish without being too gaudy and over the top. The acting is top notch from everybody involved.
In a word, it was great!
