The first three episodes of The Mighty Nein were good (though they're going dark right away with some stuff.) Very different from the start of the Actual Play but I actually like most of the changes. They're tightening up some character arcs and seem to be setting up a more logical progression to where things up. (Which makes sense, since we as viewers have different story expectations from an actual scripted media than we do from an improvised story with dice.)
Lots of wailing and gnashing of teeth from some parts of fandom about some of the changes. But that's pretty much expected for any adaptation.
