I say most of the hate generated are because he posts scientific stuff and he is too skinny to back it up. Once he gets bigger, I'm willing to bet no one would point him out.

Correct me if im wrong.

Your hips shot up a little early.

Yeap based on the vid, you use your legs to pull/drive the bar up and use you lower back to lower the bar.

Nevertheless, there's still room for improvement! 

Bar too far from your shin. Place the bar over your mid foot.

Your hips raise up first because your hip starting position too low. The starting position don't have problem but just not perfect for your body. Check your video, your hip starting position should be the same as your bar start to leave the floor.

Don't hyper extend on top.

Your form is really stable and just need few minor adjustment. If you worry, post again next time using heavier weight.

Just my 2 cents. =)
