This came up as a random Amazon movie suggestion after we watched another Scooby Doo movie. I'd never heard of it but I'm so glad I agreed to buy it. Daphne and Velma rock as role models. Daphne finds out that what she thought was luck for the first 15 years of her life was actually her father following her around and fixing stuff. What does she do? Demand he stop, determined to take care of herself, even if she embarrasses herself. This Daphne is totally plucky. And Velma is wonderfully geeky and self aware.
There is no Fred or Shaggy or Scooby and they are not missed. There are subtle nods to the original, such as one scene where Velma happens to be wearing an orange turtleneck. There are plenty of holes in the story, and some reality stretching, but that's also true to the original. I can watch it multiple times and not be annoyed, and most importantly, the movie has a matter of fact message of female empowerment that is still missing from most films about teenage girls.
