“”Ghost World”” — Growing PainsDirector Terry Zwigoff’s last movie was the off-kilter but fascinating 1994 documentary “”Crumb,”” a profile of the way-eccentric alt-comic auteur whose jaundiced worldview and ultraviolent, ultrasexualized fantasy scenarios fly way under the mainstream comic-book radar. Another cartoonist of the same ilk is Daniel Clowes, who along with Zwigoff adapted his graphic novel “”Ghost World”” for the screen here. What this coming-of-age/unconventional love story lacks in narrative propulsion it almost makes up for in whimsical, arty sensibilities and its sharply-etched, colorful protagonists.
