What’s on TV
DC’s LEGENDS OF TOMORROW 9 p.m. at CW. Last season, the legends rejoiced after killing the time of demon Mallus with a wild animal. In this season 4 premiere, the team Ava (Jes Macallan) and the Time Bureau unite to take care of the remaining anachronisms, but reach a big hump when they learn that their defeat by Mallus released a wave of deadly magic creatures across the timeline. Their quest for evil unicorns, fairy-godmothers and other deceptive creatures leads them to Woodstock.
T.I. & TINY: FRIENDS & FAMILY HUSTLE 9 p.m. on VH1. One year after the reality series “T.I. & Tiny: The Family Hustle” packed up his six-season race, the Grammy-winning rapper and his family are back for this new show. This time they are joined by some Houston friends: the songs Monica and LeToya Luckett and the author Toya Wright. Each throw member has its fair share of luggage, so expect a mountain range in drama.
