What is the worst comedy series finale of all time?
How I Met Your Mother's "Last Forever" (2014) is the worst comedy series finale of all time. Two and a Half Men (2015) and Seinfeld (1998) follow. The pattern: comedies whose final episodes were written from a place of contempt — for the audience, the characters, or the show itself.
Worst Comedy Finales #1–8
| Rank | Show | Finale | Year | Why It Failed |
|---|---|---|---|---|
| #1 | How I Met Your Mother | "Last Forever" | 2014 | Killed the Mother in a montage. Reunited Ted and Robin in the final scene. Nine seasons of buildup undone in 40 minutes. The DVD's alternate ending is the canonical fan-preferred version. |
| #2 | Two and a Half Men | "Of Course He's Dead" | 2015 | Chuck Lorre's extended public feud with Charlie Sheen, staged as a series finale. A piano falls on Sheen's stand-in. Lorre appears, says "winning," and is also crushed by a piano. |
| #3 | Seinfeld | "The Finale" | 1998 | The gang stands trial for years of selfish behavior. Witnesses across nine seasons testify. They're convicted. Meta-commentary fell flat for 76 million viewers. |
| #4 | Roseanne | "Into That Good Night" | 1997 | Reveals the final season was Roseanne's fictional novel, rewriting Dan's death. Undoes the entire season. The 2018 revival ignored this ending. |
| #5 | Will & Grace | "It's Time" | 2006 | A 20-year time-jump that separated Will and Grace for two decades, then reunited them at their children's wedding. The 2017 revival famously erased the entire finale via dream reset. |
| #6 | Glee | "Dreams Come True" | 2015 | Time-jumps five years to a Lincoln Center memorial. Cory Monteith's absence, off-screen events, and a montage-driven structure left fans cold. |
| #7 | That '70s Show | "That '70s Finale" | 2006 | Topher Grace and Ashton Kutcher's reduced presence in the final season made the New Year's Eve countdown finale feel like a coda to a show that had already ended. |
| #8 | Dexter (cynical-ending comp) | "Remember the Monsters?" | 2013 | Included as a comparison — Dexter's lumberjack ending shares a cynicism pattern with the worst sitcom finales: ending a long arc by abandoning, not resolving, the audience relationship. |
