This episode was simply astounding. The music was hauntingly beautiful, the visuals... well it's Sam Esmail, we already know what we're getting. The tension from the Janice subplot was absolutely arresting, and the main plot had several hard-hitting moments. Especially, of course, the final scene; that is genuinely one of the single best scenes of anything I've ever seen, probably top 5. My previous favourite before this was Kill Process but this episode simply had everything. I now truly believe Mr. Robot is the best series ever made and I didn't think I'd be saying that about another TV show for much much longer than this, but Sam Esmail and the crew have created a modern classic, and it's not even over yet.
