The movie's pretty neat and I like it alot, but... (spoiler)
The sneeze killing method was lame, cringeworthy and out of sync with the tone of the rest of the movie.
The tech depicted in the movie were kinda near future and quite realistic, like robot arms and very few autodriving cars. Most other cars used by regular people are still normal cars.
The chip in particular was a really new invention, inordinarily advanced, a breakthrough. So I guess it's quite makes sense.
Hell, why they even have arms implanted with guns if you can simply kill people with a sneeze. That's just ridiculously over the top.
