I'm only going to counter the ones I know about. [quote]Why didn't Frodo just fly those winged monsters all the way to Mt. Doom?[/quote] Because the ring corrupts even the most noblest of creatures. Actually, especially the most noblest of creatures. This is why Gandalf refuses the ring absolutely. The Eagles aren't any different. [quote]Why didn't somebody just use Avada Cadavra on Voldemort's snake?[/quote] It was a horcrux. It had to be destroyed by the sword of Gryffindor or a Basilisk tooth. [quote]Why doesn't Goku just use Spirit Bomb in every fight since it's an OHK?[/quote] Because it takes like 298817897189109 million years to charge. It may as well be rendered a useless attack unless the opponent is practically immobile. [quote]Why didn't Ripley just kill the Alien Queen right away?[/quote] Because she was aware there was eggs and [i]lots[/i] of guards protecting the Queen. [quote]Why would Bane give Bruce a doctor and an exit out of prison if he wants him to suffer?[/quote] That's the point. Giving him meaningless hope [i]is[/i] suffering. Probably the most effective way there is to it. [quote]Why didn't The Avengers just use The Hulk on Loki when they had him in custody if it would just end the war sooner?[/quote] ....You went full retard. 1) They didn't know how to control Hulk. 2) It would be completely counter intuitive to release an uncontrollable, unstoppable beast just to kill Loki of all people. 3) They wanted him alive for questioning. 4) Thor wouldn't have had any of it. 5) Killing him probably wouldn't have stopped anything. [quote]How come the Cog's don't just use The Hammer of Dawn in every battle with the Locust?[/quote] There were limited satellites and most fighting took place underground.
