The “Barney” meets “Network” satirical plot is set into motion when manic kids' show host Rainbow Randolph (Robin Williams) is busted for accepting bribe money from parents hoping to get their tykes on his program. Desperate to find a replacement for the disgraced Randolph's now-vacant time slot, execs from the network (Jon Stewart from TV's “The Daily Show,” “Being John Malkovich's” Catherine Keener) take a chance with a bottom-rung song-and-dance man (“Fight Club's” Edward Norton) whose painfully earnest act as the fuchsia-colored rhino “Smoochy” at least doesn't seem to pose any risk for further scandal. But when “Smoochy's Magic Jungle” becomes a surprise hit, an increasingly insane Randolph devotes himself to wiping “that one-horned carpetbagger” from the face of the Earth.
The wandering, unevenly structured “Smoochy” eventually overstays its welcome, losing much of its momentum in its too-long final act, but Adam Resnick's screenplay and caustic song lyrics (set to tunes by composer David Newman) supply some wickedly funny moments along the way. Williams has flashes of his old comic genius as he dives into his character with malevolent glee, seemingly trying to make up for the string of warm and fuzzy roles from his recent “Patch Adams” phase in one bile-dripping villainous binge. As with past DeVito efforts in the genre, opinions are sure to be polarized over how amusing the overall package is, but there's no denying the filmmaker has accomplished the “dark” part of his dark comedy mission.
