This will be brief, and I’ll only mention one thing I’m disappointed with, from the last episode, even though there were some other issues throughout. I like the series, but the plot-hole at the end was too big to ignore.
Obviously this contains a spoiler, so don’t read on if you haven’t watched it.
At the end of the episode, a device is about to explode everybody’s brains, all humans, and end the world. So Supergirl has no choice but to fly it out into space where it will be harmless. The problem posed in this TV universe though, is that she will not be able to return from space once she gets there as there is no atmosphere and she will have no thrust. Also she can’t breathe. So she had to be rescued by her adoptive sister, using her Kryptonanian pod. (How? But never mind. That’s not my complaint.)
Now even though Superman and Supergirl of the comics could always fly in space, and didn’t need to breathe, this could be a valid plotline. Sure, they are free to decide on their own rules and limitations of the characters for their TV Supergirl universe, so like her blue heat vision, her being unable to fly in space falls perfectly within what the creators of this show can do… But there’s a problem.
Near the start of the previous episode, the reason that her cousin, Superman, could not help her, was explained as he was “off-world”. It would not make sense to assume that he used the pod that brought him to Earth as a baby. It would make sense, when stating that such a character was off-world, to assume that he, you know… flew out into space.
And that’s a massive plot-hole. Unless you’re a child, and I gather this series is not especially for children, that’s enough of a plot-hole to ruin an otherwise good story. I can understand their reasons for not being able to show Superman, but the story that he was off-world and the plot where it is unsafe, and almost certain suicide, for Supergirl to fly out into space, directly contradicts itself. I looked past all the cheesy dialogue earlier in the series (her aunt referring to her as “my niece” and so on) and I looked past the casting of the annoying as hell living scarecrow, Calista Flockhart, but this… this is terrible writing. Now I wonder if the show will be renewed for a second season after all. If it is, I hope the writers do a better job and write stories that make some sense. At least stick to your own rules, for fuck’s sake.
