Crisis on Earth X introduces Jenni Ognats XS from Legion of Superheroes.
The first 2 episodes of this crossover were great. They did such a good job with all the characters. Sara and Alex, Grey and Jax, Ollie and Felicity, Stein and Caitlin had a nice scene.
The best couple of the night had to be Rory and Caitlin
Conversely, the worse couple was the Fuhrer and her mate(Nazi SG and Evil Ollie).
LOVED the return of the original Reverse Flash (the Wells version of Thawne). I remember Tom Cavanaugh saying that Thawne was his favorite Wells to play.
