It's FUNNY. Simple as that. This, from a guy who very, very rarely LOLs at at TV show, and who can almost always resist spending an entire weekend binge-watching a TV show. I LOLed, and I binged. Thankfully, I knew there were only three seasons. If I ddin't know that, I would be very, very angry at Netflix, and would seriously consider rage-quitting. There are plenty of other streaming services, with tons of great content.
The last time I LOLed (and boy, did I LOL) was the scene where Sheila and Joel were discussing the morality of killing and eating a wheelchair-bound neo-Nazi, after listening to said Nazi's diatribe on being treated like a second-class citizen. In the end (I won't give away the fate of said Nazi) Joel says "I guess we should go home and read up on moral relatavism",. i almost choked with laughter (out loud).
Seriously, how can you NOT laugh out loud? How did LOL ever become a thing? It doesn't make any sense ..
