I liked the third season of Legends of Tomorrow better than the first and second. Rip Hunter is better as a guest star than as a regular--less portentous--and it's always great when John Constantine drops in.
Phone Home (# 4): Singin’ in the Rain, Fiddler on the Roof, and E.T!
Helen Hunt (# 6): Jax/Stein body switch; Hedy Lamarr!
Crisis on Earth-X (# 8): will miss Victor Garber
Daddy Darhkest (# 10): John Constantine!
Guest Starring John Noble (# 17): John Noble (as Denethor) recording lines as Mallus (voiced by Nobles)
The Good, The Bad and The Cuddly (# 18): Beebo!
Looking forward to season 4.
