BBC America's ''Friends and Crocodiles" made me think of the writer D.H. Lawrence. As great and original as he was, Lawrence sometimes turned his characters into sharp instruments for his ideas. Rather than shape his people into well-rounded human beings, he built them as mere vessels for broader social, cultural, or natural concepts. The concepts were interesting enough, but they could overwhelm a novel's fragile psychological realism.
This new movie, written and directed by Stephen Poliakoff, forcefully charts the economy of the 1980s and 1990s from boom to bust. But the characters are quite secondary to Poliakoff's larger points about how dreams were born and how they died in two decades' time. Indeed, ''Friends and Crocodiles," tonight at 10, functions more successfully as a socioeconomic study than as an engaging story about a wealthy venture capitalist and his officious assistant. The characters border on unbelievable, despite the actors' best efforts.
