Creating separate list of a custom content type for every user I have a custom content type named Movie.

Every user must have 2 lists of movies :-

1) Seen Movies

2) Unseen Movies

For this purpose a ADD button (or 2 buttons - 1. add to seen, and 2. add to unseen) should appear on every movie page , by which a user can add the corresponding movie to his seen list or unseen list. 

How can i do this??

I am using Drupal 7.

I am new to drupal, so what should be my approach to solve this problem ?? Please help :-)

THANX IN ADVANCE
I would take a look a the flag module. It allows you to create an unlimited number of "flags" that can be placed on nodes that users can select/deselect. You could create one for "seen" and "unseen".

It has views support so you can create a view using the user id as an argument on each user's page that will show them which movies that have flagged.
