Until VH1 recycles it’s “I Love the 80’s” series again, those homesick for the era have two choices opening in movie theaters this week that are both affectionate tributes to the era. It makes sense — studio executives in their 40’s and 50’s came of age to the music of Bon Jovi, Guns n Roses, Def Leppard, Joan Jett, Jefferson Starship, Journey, and Foreigner, so the prospect of a juke-box musical like “Rock of Ages” is irresistible. And Adam Sandler, whose movies are always in some way about the 80’s, populates his new film, “That’s My Boy,” with 80’s figures like Vanilla Ice, Tony Orlando, and Todd Bridges. His character’s most meaningful gift to his son is a feather earring from a Loverboy concert. Reviews of both will be posted in a few hours.
