Why leak an unfinished movie that people spent years of hard work making it, not to mention millions of dollars that went into production!

I have a lot of hope for X-Men Origins Wolverine! As a comic book collector I have been waiting a long time and this is a golden age. Then some retard steals the movie and puts it on the web unfinished. A lot of the criticism trying to rain on my parade are bashing their assessment based off of an unfinished work print that is said to be missing some footage and a lot of effects. It's a shame!
