Love wanted its series finale to match the Seasons 1 and 2 endings

The Hollywood Reporter

"For us," says Paul Rust, "the goal was always to try coming up with an ending that was complicated, and that it might have the optics — to use a word everyone loves — where it looks romantic, but maybe underneath it, it's a little bit dark... or the optics of it might be that it looks dark, but underneath, it's actually sweet. In broad terms, that was the goal: making sure we had an ending that felt like it was a little layered." ALSO: Judd Apatow on whether Love could've lasted for more seasons.
