It makes perfect sense because:
• Sinestro is one of comic book's most complex and badass villains of all time wielding one of the strongest artifacts from the DCU.
• Sinestro is THE key to the Sinestro Corps War.
• Sinestro has been established as a presence.
• Sinestro has a connection to one of the members of the League.
• Strong's Sinestro was universally praised by the critics and fans despite the film flopping and panning.
• Sinestro makes more sense than Despero, Amazo or Starro.
The first five points are only reasons why he should be the villain in a second Green Lantern movie, which won't happen, so obviously you just want him to be the villain in JL because GL2 won't happen.
Sinestro doesn't make more sense than Despero, Amazo, or Starro, give me 1 good story where Sinestro alone takes on the JL. He is a solo movie villain, accept it.
I'm sure much of the fanboy community would be dissapointed if he was the main villain. Despero Amazo and Starro are established JL villains, therefore they make much more sense than Sinestro.
He is much more suited to be a member of the Injustice Gang or Legion of Doom, which is the role he ALWAYS plays when he takes on the JLA. He has ties to one of the leaguers? The one member who recently had a complete FAILURE of a movie? Seriously man, let's get someone who is a bigger threat than Sinestro. Hal can beat him by himself, why would the whole JL be needed to fight Sinestro when the ONE Green Lantern can take him on by himself and win?
Hal has the whole corps to back him up, why would he need the JLA to beat Sinestro? It makes no sense to me. Let's use an established JL villain who can pose a threat to all of the JL.
Plus, if included, wouldn't this put the focus on GL? Of all the great villains that havent seen the big screen, why use one that has already been in a movie, and a failed one at that?
Let's give someone else a try, someone the fans have been wanting to see for a long time...
Someone like Darkseid, Starro, Amazo, Despero or Brainiac
PS, I don't think anyone wants to see the Sinestro Corps War be the story of JL movies, that is much more suited to a Green Lantern movie.. We need something that has to do more with the other leaguers rather than just Green Lantern............................
