Mirrormask is not the most usual selection for a family movie night, especially on Mother's Day. In my house, though, Neil Gaiman is like unto a god. He wrote the script, so, we used Comcast Direct to order the movie. We watched about 5 minutes of it, and the sound disappeared. We stopped the movie, and started it up again. Same problem.
It is awful to start to get involved in a movie and then have to stop watching it. So we hopped in the car and drove to Blockbuster, and rented it. Raced home and advanced to our previous stopping point. And were really glad we did.
What an amazing, odd and wonderful movie. I was absolutely mesmerized. I highly, strongly, emphatically recommend the film. But don't watch it if you are too tired, or under the influence of any mind altering substances, as it is rather hallucinogenic all on its own.
