For five years this wasn't one show — it was two shows sharing one universe in real time, trading characters, phone calls and apocalypses week to week. Then a network split cut the line mid-conversation. We mapped Buffy and Angel the way they actually ran: side by side, year by year.

Season by TV year: Buffy on the left, Angel on the right, and the dashed rows are the actual crossover traffic between them that year. When you hit 1999, start watching them together — that's how the story was built.

Everything on screen — release order
The 1992 film is the odd ancestor: Joss Whedon wrote it, hated the comedic tone it got, and rebooted his own script as the 1997 series. The show treats the movie's events as loosely canon — just not the movie itself.
The character shuffle — who crossed the lot
The Buffyverse's signature move: characters didn't guest-star, they moved. Sunnydale's rejects became Los Angeles' heroes. Follow the routes.
The Big Bad ledger — one villain per season, both shows
Buffy invented the modern "Big Bad" structure — TV seasons built around one escalating villain. Here's the complete ledger. Angel bent the rule: its true Big Bad, the law firm of Wolfram & Hart, spans all five seasons.
Buffy — Sunnydale
Angel — Los Angeles
The Slayer line — one girl in all the world (until there wasn't)
The mythology's spine: when a Slayer dies, the next is called. The line's twist is that it runs through Buffy's first death — the two minutes she drowned in season 1 — not her second. From then on the "one girl in all the world" rule has a loophole… and the series finale drives a truck through it.
Where to start — routes through Sunnydale & L.A.
The honest advice: the high-school years stand alone beautifully, and from 1999 the two shows are one braided story. Pick your commitment level.
Beyond the screen — canon comics, lost shows & the reboot that died
The Buffyverse kept going after 2004 — officially — in comics Whedon ran like TV seasons. And it kept almost coming back to screens for twenty years without ever landing. Here's the full extended file, honestly labeled.
