This Is It Was A Disappointment

After being hyped to the extreme, the Michael Jackson documentary This Is It is selling pretty short.
The film made $20.7 million over the Halloween weekend, which was much less than Sony had expected. Paranormal Activity followed close behind with $16.6 million.
Sony execs apparently think that the initial talk of sold-out screenings during the pre-sale has kept fans from turning out to see the movie.
Seems like Sony was way off the mark when calculating the public interest.
Did U see This Is It? What did U think?
