"All Dogs Go to Heaven 2" is OK as an animated musical fantasy for children, but it's likely to be a bit of a yawn for their parents. In the 1989 original, the mutt, Charlie Barkin, was dispatched to heaven after he was rubbed out by Carface, his bulldog partner in a Louisiana nightclub, which led to a trip back to earth for revenge.
A raffish scam artist, Charlie (voice of Charlie Sheen, taking over from Burt Reynolds), is bored by heavenly nothingness when he's assigned to return to earth once again, this time to retrieve Gabriel's horn, without which the gates of heaven won't open. Accompanied by his dachshund pal, Itchy Itchiford (voice of Dom DeLuise, as before), Charlie heads for San Francisco, where the horn landed.
Once there, he encounters Satan's minion Red--a cat (voice of George Hearn)--appropriately headquartered in Alcatraz, whose own sidekick is none other than fallen angel Carface (Ernest Borgnine, taking over from the late Vic Tayback). Charlie is also beguiled by a beautiful Irish setter, the aspiring nightclub chanteuse Sasha La Fleur (voice of Sheena Easton), who in turn has befriended an 8-year-old human runaway (voice of Adam Wylie).
Directed by Paul Sabella and Larry Leker from a script by various hands, "All Dogs 2" is needlessly bland, with its Runyonesque "Guys and Dolls" milieu and the distinctive architecture and atmosphere of San Francisco only vaguely evoked.
