Sometimes, no matter how hard you try, you just have to go. And if you have to go and you're watching a good movie, deciding when to make a run for the bathroom could be difficult.
You don't want to miss something good.
Now you don't have to.
RunPee.com reviews movies for the specific purpose of giving you the 'all clear' when it's okay to hit head. Like the above review for Star Trek. A movie I finally plan to see this weekend. According to runpee, about 50 minutes in to the movie you'll have a good 3 minutes to go relieve yourself without missing much Star Fleet action.
It's nice to know I can bring a large soda into the movies once more.
