So that wasn't that great, was it?
Overall the show has had a handful of good episodes, but I feel like this finale kind of summed up the series' strengths and weaknesses rather well: it has heart, it really captures the right tone of a Super-person story, and it has some genuinely nice character moments (I think Kara's goodbye to J'onn was a really good scene and my favorite part of the whole finale).
But that's all kind of buried under a very thick of cheese and lame writing decisions, weak villains, and plot devices that, even by a superhero show's standards, are really contrived. Alex saving Kara was especially bad. How does she know how to fly the pod? How did she get it out of the base and up to where Kara was in literally seconds? How did she even retrieve her? She wasn't wearing a suit -- did she just use the ship to nudge Kara back down to Earth (and through the atmosphere)? Plus that cliffhanger, come on.
On a brighter note, while J'onn is my favorite of the cast, I've grown to really like Cat and Max Lord too.
Not terrible, but an unsatisfyingly mediocre note to end on. The show has had some good episodes but these last two were not among them.
