Limbo is coming. That long, seemingly endless expanse of time between the end of camp and the start of school. Some of us are lucky enough to be vacationing, but some of us are trapped. In the heat. Listening to that ongoing, juvenile chant: "I'm bored. I'm bored. I'm bored." In some cultures children say "What do I do NOW?" but it's all the same meaning: For the last two weeks of August through Labor Day, families need activities. Preferably ones that involve air conditioning. In the often fruitless search for movies you can actually enjoy with your kids, it's always nice to hit the jackpot, and tomorrow movie-goers across the country just may: The Odd Life of Timothy Green is a movie you can actually enjoy with your kids. And it will take up whole hour and 45 minutes. Plus previews.
