Angel
The spinoff takes the parent show's structure and drops the jokes: Darling Violetta's 'Sanctuary' instead of surf-punk, city at night instead of monster movies. Like Buffy, the design holds for five years while the names in front of it keep moving.
Season 1
48sThe first year, with Glenn Quinn credited as Doyle — a billing that lasts nine episodes before the character is killed off, making this the shortest-lived name in either show's titles.
Season 2
50sRe-cut, with J. August Richards added as Gunn.
Season 3
50sAmy Acker joins as Fred.
Season 4
48sVincent Kartheiser is added as Connor for the season the show spends pulling itself apart.
Season 5
45sThe last and largest change: James Marsters brings Spike across from Buffy, and Charisma Carpenter — in the titles of one show or the other continuously since 1997 — is gone.
