I guess I'm against the norm here haha. I find early reviews (and ratings) useful. Unless, of course, the review is before the drama actually airs. :o But otherwise, if I am lacking time to watch all the currently airing dramas I would like to, the up-to-date reviews help me choose which are worthwhile to watch now. If the drama turns out to be not so good, I'll just move on to the next. Also, doesn't the review here ask you at the time of writing how many episodes you've seen?
