What can you do in just 30 minutes? You could cook a decent pan fried chicken and veg, or run to your local, down 2 pints and run home again. I also have no doubts that, in the near future, you could order a trampoline from Amazon and have it delivered directly to your door.
But none of those are particularly useful if you're just looking for something to watch on a brief train journey. Thankfully, Amazon's streaming service also has some fine examples of shows that are tightly scripted and produced to run in 30 minutes or less.
