Lions don't roam in sub zero temperatures and never seen in Himalayas,
Physics has no link with this movie,
They have no idea what they are trying to explain to the audiences,
The female lead looks like she's posing for a magazine photoshoot in every other scene in a sub zero environment,
They fell from 100s if not thousands of feets towards the bottom of the mountains where there are rocks and permafrosts and not even scratches were found on them,
There's no such condition where the body turns blue by just touching the skin,
No long ropes were found in previous scenes but they magically appear in next scene,
Boomerang can't hook on to a permafrost,
The magical herb aka bioluminescent mushroom should have just flew away with such fierce wind blowing while the guy was falling to his certain death,
How the hell did he survive after impaling himself on the vital nerve on his neck and nearly bleeding himself out and escaping from a lion on top of the Himalayas and falling thousands of feet to the bottom of the mountain...
