I found Tomorrowland visually stunning, however the plot was convoluted especially for the younger set and was about 45 minutes longer than it needed to be.
Parents can be comfortable in taking the children to see this movie. There are several good role models and the violence is kept to a minimum.
Tomorrowland does attempt to send a message to the audience about our earth and the need to care for it now, but the message became a bit verbose. I wondered how Disney was able to land George Cloony for the lead role. After seeing the movie I believe George found Tomorrowland the perfect platform for doing the thing he does best — trying to save the world.
