Things I learned watching The Meg
1. You can out-swim a 25+ shark in the sea without even wearing swimming fins.
2. The best way for a person to tag or shoot/and poison a Megalodon is by jumping in the water with it.
3. At no time call and warn the Navy. It's not like they might have better weaponry and skills in dealing with threats underwater at sea.
4. At all times, the best way to fight the biggest shark to ever exist is for Jason Statham to constantly get into the water with it.
