Aliens invade Earth! This was the best crossover of the first 3 seasons by far! It laid the foundation for all the others going foward. Before this it was just Flash and Arrow with stand-alone episodes. Now it was everyone! It had Flash, Supergirl, Arrow, and the Legends in an overarching story spanning 3 episodes. Aliens are always fun and so is mind control! What's not to love? The Flash episode isn't as good as the Legends of Tomorrow episode, but that was a high bar to reach. All in all, I love Invasion, all three episodes are a fun ride especially this one! The only issue is that every Invasion episode didn't feel like it was the same story, but that's a problem with the crossover as a whole and not this episode in particular. 100% awesome the whole time!
9/10-Great!
