Physically and medically impossible
SPOILERS!
Why is this still acceptable to have an bionic arm or leg to give super powers that would require the same strength in the connecting body? In the main characters case, his pelvis would break and tear itself to pieces, or the bionic legs would rip off if he would exert too much power with his bionic calf muscles. It's simply impossible and doesn't make sense!
The same for crazy arms, he is basically wearing METAL GLOVES. So if I put on metal gloves, how then am I able to smash a column of concrete, since all the strength would have to come from my arm, shoulder, spine and even legs to exert that kind of force?
And while we're at it, even if the main character still has genitals, how in the world doesn't he have "scrambled eggs" after running like 100km/h? Or why isn't his head bashed in after running through the glass in the end?
Even for a science fiction, you should get fundamental physics and logic right. I'm surprised no one complains about this, because I'm incapable of suspending my disbelief when watching stuff like this.
Otherwise, it was not a bad film, but stupid writing is stupid.
