I watched this half expecting some in depth investigation into the seedy side of cam life, but yes as one other reviewer reported it's nothing more than a promotional film.
I have looked at cam sites previously but to be honest it's not my thing, and I certainly wouldn't throw money at the performers and the same applies to lap dancers and hookers etc.
I did check out what was a relatively new player to the scene freewebcams, who during the documentary had won some kind of award. Well what a turn out for the books, this award winning new business had just 4 cam girls online, and taking another look some 10 hours later the site was offering just 1 girl online with 22 watchers. After 5 minutes she gave up so now there was no live cam girls online.
Obviously if this is anything to go by making a huge amount of money by setting up as a webcam business or becoming a web cam model is not as easy as it would appear.
Or maybe there is some kind of reverse psychology in play, you purchase a shed load of tokens out of pity for the girl.
As a doc it was just about watchable, it's not one I would choose to watch or recommend. 4/10
