Roy's letter is 100% accurate and to the point.
Take a careful look at Disney since the release of the Lion King in June of 1994. If you find a single sustainable success notify the financial press, as they certainly have not found one.
Beyond the extremely poor financial performance since 1994 (and yes, Roy's letter points out and thanks Eisner for the superior performance from 1984 - 1994), the company is in shambles. Frank Wells is dead, Jeffrey Katzenberg is gone, Michael Ovtiz' tenure was one of the most stunning failures of all time (let's see, a $100 million payoff to go away, about 100 million shares outstanding at the time, every single shareholder was effectively hit for $1 a share on that one), and the managerial talent continues to leave.
ABC? Enough said. California Adventure? Same.
Disneyland Paris? From horrible to acceptable, and now headed back down. Animated features? Complete hit and miss. Live action features? Hit and miss again, with more to the miss. The Disney Channel? Well in the mid 1980's it was wonderful, now find once success beyond Lizzie McGuire.
Eisner did a great job for 10 years, but since then a complete disaster.
Look at the Board of Directors has been effectively purged of anyone who isn't a "Michael guy." Any truly independent directors (Stanley Gold, Roy E. Disney) have been chased away, leaving nothing but those who owe their position and allegiance to Eisner.
And lastly (mentioned in Roy's letter), what about a plan for succession? Let's see, the current CEO has been in the position for 20 years, has a history of heart troubles, and not only has no plan for succession, he has chased away anyone who possibly could ascend to the position.
Sorry, but Eisner's reign, and you can call it that, can be clearly broken into a 10 year golden age, and a 10 year disaster. Anyone who challenges him about the recent performance of Disney (in the stock market, the film market, the theme park market, any market) gets painted as the bad guy and chased away.
I'm still headed for Orlando twice this winter (once for the marathon, and once in March), and I still have a soft part in my heart for what Walt created, Ron Miller almost ruined, and Eisner turned around twice (up, then down). But it's time to GO.
