Saw a few screenshots and thought I might give it a shot, but the reviews I've read have all been terrible. Probably has something to do with the creator saying he's never seen Game of Thrones and that he's "proud that if you like GoT, you won't like Britannia," which is a fine way to alienate like...a massive audience, on purpose, for seemingly no reason.
Now actually looking at the trailers I can't imagine that I'll like it.
