That's because, even if it's a blurry pic, you can see the haunted house got the right proportions and and a architecture style that looks real which is appealing - Town Hall don't. First, Town Hall should have been stand alone, but if not it should at least look like a real house! Since the first pics I try to like it, but I can't. The haunted is on the other hand an instant buy.
Could we agree it doesn't matter which genre it will be released in! It's not like cheating on your wife if you buy something from a theme you weren't planing to. Who cares! It's Lego, that's good enough for me.
