As someone who happens to be an actual fan of the Sandman comic, I'm very glad that the show is being received positively. Gaiman is the kind of creator that can be trusted to know what he's doing, and him being this involved with the adaptation of his own masterpiece can only be a good thing. Grey, I absolutely encourage you to pick up the comic, it's brilliant.
The Hobbit trilogy mostly suffered from Jackson trying to make it a whole lot more epic than it needed to be. The first movie was alright, not great, but it had that adventure feel the Hobbit is supposed to have. The following ones felt more like wannabe Lord of the Rings, which really doesn't work with the type of story the book was written as. As for the Rings of Power, I don't really have any expectations, but I kinda hope it'll be awesome, just to spite all the haters who wrote it off before seeing it.
