My favourite reviews are the ones full of analysis. Where they ask questions or ponder events that occurred, or when they question motives or make guesses at what will happen after a cliffhanger. I love it when they say why they love or hate characters and who they think the chars should hook up with. Those are the reviews I go back to years later for a little motivation when I'm lacking. Of course, I love the concrit, the blatant praise, and the quick li'l, "plz rite more"s too.
