AMID THE USUAL SPATE OF PARADES AND BOWL games accompanying the calendar rollover are a couple of worthwhile programs. In CBS's Face of a Stranger (Sun., Dec. 29, 9 P.M. ET), Gena Rowlands plays a society matron who befriends an addled homeless woman (Tyne Daly). Both actresses are good, but Rowlands's poignant performance truly deserves Emmy consideration. In This'll Take About an Hour on HBO (Sat., Jan. 4, 10 P.M. ET), comic Jake Johannsen trains his inventive and amusing paranoia on subjects such as air travel and telephone repairmen ("If you go out for five minutes, the guy will be there. I don't know how they do that. I think as soon as you call, they put your house under surveillance").
