I bought this for a British film narrative module for my BA in English literature. It was useful in my wider reading for all my research. It does not go into great depth about any one film but gave a good overview which was particularly useful for understanding film genre.
I use this for running, walking the dog and mountain biking. It is small enough to get under a fleece but takes my mobile phone, doggy bags, tissues and car keys with no problem. I just wish the two loops for the straps were black rather than white, as they look a bit tacky. But overall I love my waist pack and think it will last me many years.
