Movie Is 'Riveting'
But Jackie Jackson -- who saw the movie on Thursday night -- liked it a lot, telling TMZ:
"My brother's movie 'This Is It' is truly riveting. Michael is electrifying! We get a glimpse of a true genius at work. His passionate message for healing the world, saving the planet and our children's futures is something he was always striving for in his lifetime."
So far Katherine Jackson is unmoved -- we hear she will not see the movie.
