Making Tech fail just for drama's sake is weak writing.
It's the same as killing off a
Red Shirt Trope for cheap Drama Points.
We should be moving past using old tropes like killing off Red Shirts.
As a creative society, all those old tropes should be defeated, thrown out, and logic should be used.
If you want to kill a character, it needs to be earned.
I would like to see a show portraying competent people dealing with problems with intelligence and facing a competent adversary that uses intelligent ways of doing whatever evil deeds they plan on doing.
So far, the DMA is a great "Weapon", if the DMA is a "Weapon".
But we need to see more competence from the main cast.
