Finished the two-hour final episode/movie. If I had to sum up the entire thing with a single adjective, it would be:
"Absolutely zero balls."
Zero stakes. The literal end of the world is supposedly happening, yet the characters always find time for long, drawn-out feelings-sharing™ sessions. On top of that, the directors clearly didn't have the guts to let anyone die in what's meant to be a high-stakes scenario.
Everything is wrapped up way too neatly, as if the audience can't handle even the slightest hint of a sad or ambiguous ending. The entire second half boils down to a lazy "and they all lived happily ever after" finale. It's not just spineless, it's cringe-inducing, with forced, fake melodrama and everyone crying on cue.
None of it feels earned. It's blatantly there to send the average Netflix viewer off with a warm, fuzzy feeling.
The whole season is slop of the highest order: terrible acting (the kids can't act to save their lives), awful exposition, dreadful writing and CGI that's mediocre at best.
There are so many shoehorned-in characters that you stopped caring about two seasons ago. The story is packed with convoluted arcs and scenarios that you completely tune out of after the second one. Add to that the obnoxious one-liner machines, the idiotic "girl-power Rambo" scenes (why not let Steve go full Rambo for once? That might've actually been cool), the ugly dude's awful haircut/fake hair, Holly's creepy child actor (that mouth, man), and on and on.
This is pure TV slop, and it once again proves that when you milk something long enough - as this show absolutely did - it completely loses its luster.
Needless, pointless, boring, convoluted, and badly directed and written.
