That utility box of whatever that gets knocked down at the beginning of the fight between Supergirl and Rhea is a great metaphor for the writing in this episode. See, it falls over and sparks and shit—looks cool, right?—but _there's nothing under it!_ No wires, no pipes, nothing. It leaves behind a blank space. It must have been there on the rooftop for a reason, right? Nope. No purpose but to get knocked over.
This episode is full of stuff that doesn't make sense, like that. Every Daxamite soldier teleports back to their ships, but Rhea stays to beg Mon-El to save her, and dies when he doesn't? Perfect sense. Mon-El has "a few minutes" before the lead in the atmosphere kills him, but manages to make it all the way to the Kryptonian pod _and_ has time to give a little speech to Kara? Perfect sense!
I admit to being emotionally affected by the drama, sure…but that lasted only as long as it took for my rational brain to catch up and say, "Whoa, wait up, how does _that_ work?!" That happened a lot.
At this point, I realize why it's taken me so long to bother finishing this season. I did stall with just the one episode left, and it's definitely because the believability of the writing is meh at best. They really do go for the "Bam! Pow! Special effects!" wow-factor without really thinking about whether that actually makes sense for the characters and the plot. It gets really annoying.
Speaking of things that don't make sense for the plot, they had a great ending tied up AND THEN RUINED IT with a teaser for the next season. I'm so done.
Wonder how many people are going to bitch about the whole "gay sister marriage" thing, so far I'm counting two posts from the same person at the time of writing this.
