Great reviews so far. As for Polygon's verdict, I haven't read it in full, but looking at the excerpt about the ghosts' "personalities," I think I know what they're talking about.
The boss ghosts in the original all had a strong sense of history -- suggested, but there all the same. For example, the twin boys were clearly connected to the father ghost and the mother ghost, even though all three of these encounters were handled separately, each in their own room, each with their own puzzles. This time around, it appears they're trying new boss characters, a number of which are non-ghosts (animals, inanimate objects, etc) possessed by spirits.
The ghosts look as entertaining as ever, however. Lots of funny stuff: ghosts tinkering with antique cars, showering in the bathroom, etc. And of course, they're put to service across multiple mansions that now function more like the dungeons in Zelda -- lots of clever environmental interaction, puzzle-solving, etc.
Sounds good. Of the three games I'm eagerly anticipating this week -- Luigi's Mansion, BioShock Infinite, and HarmoKnight -- this is the one I want to play most.
