It’s useless to try to urge the former teen actors (and those who pretended to be teens) in the bad 1990s series “Beverly Hills 90210” to redo the series 20 years later, but here they are on something annoyingly called “BH90210” (Fox, 9 p.m.) portraying fictionalized versions of themselves as middle-aged actors of varying life successes considering whether to have a reunion for said show. It begins with a drunken meeting at a Las Vegas fan convention and will continue for five more episodes. Jennie Garth, Tori Spelling, Jason Priestly and Brian Austin Green take part. Their acting doesn’t seem to have improved all these years later. Luke Perry, who died in March at 52 is given a brief tribute and Shannen Doherty is only glimpsed fleetingly. It’s not good.
