Why dont you use movies recommendation services. I like http://metataste.com very much.
It may not have good interface, but way better recommendations then netflix.
I agree. The product decides itself, how it's gonna be implemented. Things evolve with time, just you've to look the best option at that time.
I do agree too with the bootstrapping point, it's always good to be in a lean mode, if you are doing a startup and do not have a solid back support.
