Choosing data strucutures to sort TOP 10 items out of zillion items based on users rating?

It seems like there are two parallel structures here. First, you need a lookup table that can map from IDs to movies. Second, you need to maintain some sort of priority queue that can be used to track the top ten movies overall.

I'd personally use a relational database for this.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
