My girlfriend and I got really sucked into this recently. Watched all of it in quick succession despite it being pretty shit. No idea why we spent so much time on it!
I'm in the same boat. It's just sitting there in Plex waiting for me to hit play when dinner arrives. Because I'm a sucker for 'finishing' things I'll probably watched every fucking episode and hate myself for it.
Last Man on Earth. Started out like a dream (maybe I just like destruction) but rapidly turns shit.
