Superman & Lois was the last series based on DC Comics characters to air at the network. It was also the last connection to The CW’s Arrowverse (even if it wasn’t technically part of the main continuity of that franchise), which defined the 2010s for the network and became one of the more successful multi-show franchises in TV history.

Major spoilers for the series finale of Superman & Lois, “It Went by So Fast,” lie ahead.

The CW bid farewell to Superman & Lois on Monday night with an epic finale that not only closed the chapter on Lex Luthor’s terror over Smallville but also gave audiences a glimpse at the lives their favorite characters would go on to lead.
