These all have edited "soft" English captions; that is, English subtitles are part of the MKV files and the subtitles can be enabled or disabled as you wish.

I downloaded the source videos named like "Resident.Playbook.S01E01.1080p.NF.WEB-DL.AAC2.0.H.264-MrHulk.mkv" and extracted the English subtitles from them. Then I...
- Used Subtitle Edit (by Nikolaj Lynge Olsson) to find and fix all flagged issues
- Added 0.7 second to each subtitle (where possible) to allow more time to read them and adjusted words/minute to at least 280
- "Softened" all subtitled profanity (bastard --> jerk, damn --> darn, bitch --> witch etc.)
- Corrected commonly-found typos, converted many word pairs into common English contractions, and brought together sentence fragments
- Used Handbrake to create new MKV files using my subtitles, trimming off the obnoxious Netflix splash logos from the start and end
