Yep, watched it last night before going to sleep. I was late to the party with this show so have largely been able to binge all 4 seasons and only really had to wait for last night's episode to drop. Have really enjoyed the show and am sad now that I/we have to wait for the new season, and even then, it will only be drip-fed to us one week at a time. When it does eventually arrive, I think I'll need to hold firm on watching it until I can binge the whole season.
Speaking of bingeing... I believe I can watch the entire season of Slow Horses now
