I did a search, which turned up no previous threads, but this is a show from the 90s, starring Sean Bean. I've been watching it off and on for a while. The effects are.. well.. dated... but the rest is good stuff.
It's based on the novels by Bernard Cornwell. They're historical fiction, meaning the characters are mostly fake, but the setting they're in is mostly real. They're very good, as is the show. Thought you folks might like to check it out.
