i also wrote this from the top of my head after seeing the gl movie at the midnight showing in 2011
originally a idea for gl2 but it could work as a reboot
the film can open up with the weaponers go to kourgar to set up a base to start making weapons, the people of kourgar fear them as a threat and take action wich leads to violence.
: meanwile on oa on the citadel:
sinestro requests that the guardians send corps members to help aid him in defending his homeworld of kourgar from the weaponers...
the guardians refuse to send the aid and sinestro demands that the guardians step down and pass there power over to him and states that he can install great fear into the enemey and puts on the yellow ring,
witnessing the act of having the yellow ring at this moment the guardians declare sinestro a traitor to the corps and honor guard lanterns are dispatched to take sinestro into custody.
sinestro kills the honor guards in front of the guardians and relinquishes his green lantern ring by his own will and leaves oa.
the guardians summon hal jordan and request his presence and they inform him of sinestros turn to the emotion of fear and yellow energy, they also explain to hal that after krona was banished and hidden away with parallax the punishment was due to krona creating the anti-matter universe.
hal jordan go's on a hunt for sinestro
sinestro returns to his homeworld of kourgar yellow ring and costume and starts to become a dictator and declares himself savior of kourgar and starts killing weaponers left and right.
while hal jordan searches for sinestro he gets a trasmission from kilowog telling him sinestro is on kourgar and meet you there poozer..
hal heads to sinestros home sector arrives onto the planet and see's total devestation and bodies everywhere.
hal see's sinestro floating over a pile of dead weaponers with a sadistic smirk and hears him tell the people of kourgar to bow to him and worship him as a god.
hal confronts sinestro trying to explain that the yellow ring has corrupted him....
sinestro throws the first punch and says human you have no idea who your talking to.
hal responds with a fist construct hitting sinestro wile both floating in the air.
sinestro recovers and the first start to an epic encounter happens
both men fight it out with sinestro getting the upper hand and just when hal is almost out and sinestro is about to kill him, kilowog comes in and knocks sinestro off balance.
sinestro shrugs it off and fires a blast of energey at kilowog and knocks him out cold.
hal recovers and shows sinestro why hes the man without fear by taking it up a few notches.
he creates one giant construct of a f-22 raptor plane and hits sinestro with it.
sinestro knocked out falls to the ground and hal go's to check on kilowog.
back on oa the guardians place sinestro into the central power battery and credit hal jordan for his bravery
before the film ends theres two suprise scenes
scene 1. sinestro is shown inside the battery and is revealed to be a construct from his ring
scene 2. sayd and ganthet are alone in a private chamber discussing how they have to HOPE sinestros turn hasnt misplaced the trust of 3600 sectors with the guardians and they forge a blue ring
