I also have kids and that really screws up my "suggested" queue. Hmmm, should I watch "Inspector Gadget" or "The Girl with the Dragon Tattoo" tonight?
It seems to me that the rating algorithm is a bit sensitive. Also, I wonder if Netflix has considered giving people they option of multiple "personalities" for the purpose of suggestions, queues, etc. I bet if they offered this for something like $3/mo more, people would pay for it.
It looks like they explicitly remove that for streaming customers. I have no idea why.
