Nice review and discussion, I believe this pin is starting out with a handicap.
Horrendously late, like late, to make people not care about it. It's announced at same time as The Avengers pin.
People (some) don't like the movies. I'm not alone in who have watched one film and kind of could care less about the other two. Might be the other two are better but Peter Jackson butchered the movies in so many ways as to make it into a whole different animal than the book.
Some people don't like the gameplay, ramps, layout whatever. I've played a grand total of 2 games on it (2-ball at that). I was not blown away in the least. However that was last year at a pin show and didn't really get much of a feeling for it. Much like TWD I think some people would dislike it initially and later do a 180 after code and more play time.
I've had many experience where I love a game from the get go: Tron, IM, Met. But I've also had games I was meh or disliked initially that later I love such as tspp, ST, XM. I think TH is for me in the side that I'm on the fence/dislike but I wouldn't doubt given time my opinion could turn on a dime.
