TV THIS WEEK: The Mandalorian, The Hardy Boys, BattleBots and Christmas in Rockefeller

We have Star Wars, Hardy Boys mysteries, fighting robots and even an exploration of how life might've evolved on alien worlds this week — plus some Christmas programming if you're looking for something a bit more warm and fuzzy this time of year.

Disney+ is continuing to rollout the second season of Star Wars series The Mandalorian, which has introduced some true heavy hitters to live action with a story digging deeper than ever into the Jedi canon. Hulu has its moody, mysterious reboot of The Hardy Boys; and Netflix is giving us a peek at the alien worlds we can only imagine with the new science-meets-fiction series Alien Worlds. If you're wanting to robot carnage, Discovery is kicking off a brand new season of BattleBots. Want something a bit more holiday-centric? NBC has the 88th Annual Christmas in Rockefeller Center special, and ABC has the Disney Holiday Singalong.

Digging deeper, SYFY has a new installment of the puppet-tastic The Movie Show (where the crew takes a deep dive into the horror genre), plus a new Hell Den as part of the TZGZ animation lineup. CBS has the season premiere of MacGyver, The CW has a new Swamp Thing, and Showtime has the network debut of recent horror flick The Turning. CBS All Access is also dropping a fresh Star Trek: Discovery this week.
