Dallas: Season 14 (1990)

The 14th and final season of Dallas finds ruthless oil executive J.R. Ewing (Larry Hagman) escaping from a mental institution, then resuming his Herculean efforts to wrest control of Ewing Oil from his brother Bobby (Patrick Duffy). It turns out that poor Bobby may well be vulnerable to J.R.'s conniving: his new wife, April (Sheree J. Wilson), has just been kidnapped and killed during their Parisian honeymoon by the insane Sheila Foley, alias Hillary Taylor (played by daytime-drama diva Susan Lucci). Even so, Bobby is determined to keep Ewing Oil out of J.R.'s hands, and to that end his sells his interests to billionairess LeeAnn De La Vega (played by Larry Hagman's onetime I Dream of Jeannie co-star Barbara Eden!), who is determined to get even with J.R. for seducing and abandoning her back in college. LeeAnn in turn sells the business to April Stevens' sister Michelle (Kimberly Foster), now the wife of J.R.'s illegitimate son, James Beaumont (Sasha Mitchell). After murdering Sheila Foley to avenge her sister's death, Michelle breaks up with James, but not before selling half-interest in Ewing Oil to J.R.'s lifelong enemy, Cliff Barnes (Ken Kercheval). With startling rapidity, J.R.'s world falls apart. First, Cliff gains full control of Ewing Oil; next, J.R. fails in his efforts to regain his fortune by purchasing Ewing Oil; then, his beloved son, John Ross (Omri Katz), abandons him to live in Europe with J.R.'s ex-wife, Sue Ellen; and James Beaumont likewise relocates abroad with his new bride, Debra Lynn (Deborah Tucker). J.R. doesn't even own the Southfork estate any more -- it's in the hands of Bobby, who generously but contemptuously doles out an allowance to his once-swaggering brother. Besotted with alcohol, J.R. contemplates ending it all -- -whereupon a rather odd-looking "angel" (Joel Grey) appears to show J.R. what life in Dallas would have been like if he'd never been born. And it is with this perverse spin on It's a Wonderful Life, capped by another "cliffhanger," that the 14-year saga of Dallas comes to an end. ~ Hal Erickson, Rovi
