Evaluate my eBook business idea: Ebook of documentary reviews and downloads

[DragonsDen]

My friend came up with an idea for an ebook containing 100 short reviews of some of the most interesting and captivating documentaries from places like the history channel, discovery, national geographic, BBC, etc. The aim is to allow readers to discover new documentaries that they might otherwise not find, and to provide a quick guide to some of the best documentaries out there all in one place (helps the user save time by not having to search around for new shows to watch).

The ebook would also contain links to official sites, download/trailer links for people to sample first before buying, and also links to purchase these documentaries.

What do you think of this ebook business idea?

Seems like it would be a hard sell. What you could do is create the ebook and try to sell it. If it doesn't sell then give it away for free and make money on advertising.
