I think you are referring to a different phenomenon-that audiences get better or worse after they have read reviews. (Ann also mentions this below, and I do not disagree with that at all.) I took the OP to be writing about the posting of opinions that are more negative once (negative) reviews come out.
FWIW I am not someone who posts a lot of reviews/opinions on shows, but when I do early on (i.e., after seeing an early preview) it is I think always to alert folks to something I think they might like but might overlook. I cannot imagine posting to tell people not to see something but as things go on I occasionally post (in either direction) to a thread where opinions in both directions are being expressed or (even more likely) where I think a person has misapprehended something about a show. But I also think many of us have different ways of interacting with this board so it is not possible or wise to generalize. |
