Powers don’t work because reasons

There are many problems with X-Men: Apocalypse, from the dodgy script to the performances. But few of them can surpass this one. After the mansion is destroyed and Stryker arrives and kidnaps some (just some!!!) of the mutants, Nightcrawler, Cyclops, and Jean Grey jump unseen in one of the helicopters and infiltrate Stryker’s base.
And that is even if, apparently and without any explanation, Stryker has a device that nullifies all mutant powers.
That’s a pretty effective weapon, isn’t it? And it is pretty ineffective at the same time, since Jean Grey’s powers still work. I guess, in the end, the whole fault falls on Stryker’s shoulders. I don’t really know why he didn’t have that device installed in every corner of his base, thus allowing the mutants to escape…
Mind-bending.
