Tras la pared

This is a very simple and engaging french film. A very shy young pianist moves to her own apartment that's separated by a paper thin wall from another one (in another building) inhabited by a hermit (almost) game designer.

The plot is thin, but the acting's great and you really become interested in the characters. Also quite a wry comment on how our very "open" society in effect isolates people by the overuse of gadgets (read smartphones).

Anyhow, the main characters find that to have an essential connection one doesn't need to be in front of another person.

Secondary actors are also great and there are many funny and endearing moments.

Really should be seen...
