Yeah, on one hand I appreciate the writers brining all these characters into the show. On the other hand, is it that hard to stick to the origin of the twins being the kids then they haul off to the future for safety?
It might be a good shakeup for the show.
For all the criticism I have heaped on Supergirl on nitpicking their handling of the Legion, at least they took the time to pull in enough references to make that Legion (from what we can tell) recognizable.
That being said, I really liked Jessica Parker Kennedy's Nora/XS, and she'll apparently be back on the 150th episode, so I'll look forward to that!
