I just watched that snark clip about The Last Kingdom. Hilarious! I've read the series, I think its 8 books so far, 7 or 8. A page-burner, its hard to put down; with that said the author himself took certain liberties w/regard to period dress, customs and warfare. Not to the extent the show did- in the books, only the rich can afford maille, everyone else is in boiled leather and/or ringmail jacks (you know, the ones where the rings do not overlap) and tallboots, some of the wilier ones have iron strips sewn in for hidden defenses. Shieldwalls are horrific events and everyone carries a spear- which is usually thrown or tossed aside before the walls strike- then its a shoving match with sharp implements being hooked and looped over the opposing front shields. He does get gritty with it, and its enjoyable to read. I take it for what its worth, you know? Historical fiction is just that and you never know what you're going to get until you've read it- and I do get the argument that first timers will automatically assume its authentic and true because "its in the movie (or book)". Unless they're understood to be historical treatises or cited research, best to do your own due diligence because like as not, it'll be inaccurate.
