I was originally going to go with How to make a good Flash Movie first but since Green Lantern is my favorite comic book series..i decided to go with How to Make a good Green Lantern Movie that doesn't suck "Cough" Green Lantern "Cough"
The Costume:
When it comes to Green Lantern, you really need to get the costume right..while the costume in the Green Lantern Film wasn't bad..it was pretty mediocre compared to Captain America's costume in the First Avenger or Superman's costume in Man of Steel for the Green Lantern Movie Reboot..there are two images that perfectly capture what i would love the costume to look like in the the movie..


Both of these costume perfectly capture the awesomeness of the orginal Green Lantern costume while adding in some new twists..i really like the cap design of the first image and i really like the suit desgin of the 2nd image so i would love to see the Green Lantern Costume look like a combination of the first image and the second image..that in my opinion would be the best way to portray the costume on the big screen
Which Green Lantern Should they use
They is a extremely tough one..while mainly people feel that John Stewart would be the best choice to be the Green Lantern in the Reboot..i am not one of those people. While i like John Stewart you really need someone who would work best on the big screen. I know i am going to get a lot of hate for this but honestly by choice for the Green Lantern in the Reboot in none other than Alan Scott. In my opinion his powers are a lot easier to explain that the technology of the GL Corp so it would be a lot easier to focus on a more grounded and realistic charcter if you pick Alan Scott as the Green Lantern but i know it is very likely that they will pick Hal again which i don't mind, i just hope they do him right an don't do it shitty.
Villains:
It is very hard to choose a villain for Green Lantern..especially they are so many of them. I really want to go with a mystical villain that is not a member of a corp..and then it hit me..the perfect bad guys to Green Lantern..that could not only provide a challenge to Alan but also be intimidating and scary..
THE GREY
The Grey is the living embodiment of death and blackness so i think both Solomon Grundy and the Master of Death Nekron could fit very well here..i know there should be only one villain for the reboot but Solomon Grundy could be the mindless muscle who does Nekron's bidding and Nekron being the big bad guy behind it hall.. overall i honestly feel these two villains would be a fantastic choice for the villains of the Green Lantern Reboot..and they are scary as all hell..
Who should play Green Lantern
Yes..i know many people feel that Chris Pine would be good as Barry Allen..but in my personal opinion he would be a perfect Green Lantern (If they go with Hal or Alan..) Not only his a fantastic actor but he also perfectly portray Hal in the Star Trek films..hell Chris Pine did a better job at being Hal than Ryan..and he wasn't even Hal Jordan. Chris Pine is the best choice to portray Green Lantern..i really hope he is Hal/Alan in the Green Lantern Reboot
