Why did Calvin turn into a spider-web in the end?
The creature changed it's shape to brace him and ensure he made it to the ground alive. I assume, anyway. Not sure why it cares since people are gonna come investigate the capsule either way, but maybe it was hedging its best to ensure it had something to eat in the event there was nothing else around or it took too long or whatever.
The creature doesn't really make sense. There's no reason it should have known how orbital mechanics and reentry worked or have had any idea there was a planet full of food waiting for it below.
I wish that they didn't give Calvin a face. He was scarier when he was ball of tentacles
Because the whole movie is a viral marketing stunt for the Venom movie
