Alan Wake's American Nightmare: Early Impressions

So, I'm about halfway through the story of Alan Wake's American Nightmare -- from what I can tell -- and I'm really having fun with it.

It does exactly what I wanted it to do. Answer some questions, present new ones, fill in some blanks, and pay homage to the likes of that one episode of Star Trek: The Next Generation where the Enterprise-D is stuck in a time loop, X-Files, LOST, among many other sources. And even though it does all that, it still doesn't actually answer very much or at least doesn't spoon feed the players the answers to what's actually happening. Instead it allows the player to draw some of their own conclusions; write their own fiction as to why things are happening the way they are. Has Alan has actually escaped the cabin under the lake back to the real world years after the events of the first game and he's just gone batshit insane? Are the TVs and radios conduits to the real world? Is his nemesis, Mr. Scratch, living in Alan's head or is Alan living in Mr. Scratch's head? Am I just over-thinking the whole thing? Probably. But that's part of the appeal of Alan Wake, at least for me.
