Wasted potential. I think that pretty accurately describes both this episode and the season as a whole.
GOOD THINGS: Brainy turning bad, however temporary. First time in a while I didn't want to slap him for being annoying (and for replacing Winn). MB and CL reminding everyone how good they are together.
BAD THINGS: Hmm...I wonder what the character limit is? Seriously, I'll just name a few. So...Alex's mindwipe is over, huh? What was the point of that again? Other than giving Kara a couple of extra angsty moments I mean. Red daughter is dead? Maybe not, in which case I'll take this one off, but wow if she's really gone off screen like that...I have no words for what kind of a "we just gave up trying" moment that would be. Lex being viewed as a hero. Kara being public enemy number one, fine, the world at large saw it and didn't know she had a clone, but Lex is a certified, publicly known psycho, and even if they wanted to credit him for stopping an invasion how would anyone besides his presidential puppet CALL him a hero? James having superpowers in general. The Guardian thing didn't (IMO) work out so why would making him as strong as Kara? If you have to keep going to these lengths to make/keep the character relevant, maybe the character isn't working out,
SPECIAL NOTE: The sudden change from day to night when RD punched Kara. Count me as one of those who originally though RD hit her so hard she flew to the other side of the Earth or something but unless there is a better explanation coming that was some seriously bad editing.
I'm curious to see how/if the finale wraps everything up.
