Seven of Nine pushes for further individuality with a series of holodeck programs designed to research and practice social interaction.
There is a lot to admire about this episode, particularly Seven's character development and the performances of Jeri Ryan, Robert Beltran and Robert Picardo. I liked the piano metaphor during the development of Seven's social interaction skills. The link back to the Unimatrix to explain her motivation was a good idea. Also, the ending was quite unexpected and put an imaginative sci-fi spin on the outcome.
It made me contemplate numerous things such as my own personal and profession development, along with how to effectively balance the both. The nature of individuality and what defines it. Ironically, Seven seeks to break free of the mindset created by the Borg collective identity, yet she becomes obsessed with learning how to conform to the behaviours of human society. In all the episodes where The Doctor or Janeway advise her how to interact, I am waiting for her to do something wrong, argue her case on how it should be done and one of them to say "Resistance is futile".
For me this is an episode where the sum of its parts is greater than it's whole. I like all the scenes individually, but I wasn't particularly keen on an entire episode being dedicated solely to this amount of one character's development. I personally would have preferred little scenes along these themes to be placed periodically in other episodes.
