Following the success of
Buffy the Vampire Slayer , Angel emerged as not only a spin-off from Buffy but proved to be independently strong in terms of its ratings. Angel, which is also created by Joss Whedon in collaboration with David Greenwalt, stars David Boreanaz as the vampire with a soul, Angelus (later on shortened to Angel). The show chronicles the adventures of the vampire turned private detective in constant battle with the demons and monsters linked to Wolfram & Hart in Los Angeles, California. Angel's allies are Cordelia Chase (played by Charisma Carpenter), the shallow ex-cheerleader who softened at the loss of her parents' financial support, Allen Doyle (Glenn Quinn), a half-human, half-demon messenger and Wesley Pryce (Alexis Denisof), a failed Watcher.
