Actually “so bad it’s good” ∞
“So bad it’s good” films are mostly not actually a thing. I think bad films are mostly just bad, and do not become enjoyable when they reach some threshold of badness.
But “Beyond Skyline” (recently arrived on Netflix) might be an exception. Or maybe it’s the kind of bad it is, rather than the degree, because there’s a real budget here and it would fare quite well compared to many other shitty sci-fi films. But it is such a B-movie, and it is bad… but it knows it is, and that’s actually quite a fun formula.
Awesome outtakes at the end confirm the self-awareness. They are grown-ass people making a silly damn movie, and they definitely know it.
