Supergirl Season 5 Review: 6 Ups & 3 Downs From Crisis On Infinite Earths, Part 1
2. Lena The Martyr
While Lena Luthor's unnecessary heel turn has paved the way for some truly wonderful character-driven story elements, it was a complete drag on the Crisis. Yes, it was kept to something of a minimum due to the fact that Alex visited her and asked for her help (instead of Kara) but it was a conflict that felt completely out-of-place given the circumstances.
Every five minutes Lena felt the need to remind Alex - who had just saved her life - that they were no longer friends (in the most highly-expositional way so that non-Supergirl viewers would have a clue why she was behaving in such a ridiculous manner) and, quite frankly, it left viewers wanting to scream at her because it's the end of the freakin' world.
Get your priorities straight, Lena.
