Part 1 is an amazing episode, but I think I love Part 2 just as much if not a little more. Nowadays, the way to resolve something is through non-stop action and guns ablazing, This episode decided to do what TNG has always done best, take this problem, and actually solve it in a creative, kind of logical way. I like the comparison to how Picard dealt with the Shiliak because it's kind of the same thing. Riker and Data used the Borg's own system against them, just like how Picard used the contract. Like I said, it was really creative and a pretty satisfying ending.
