Green Lantern: First Flight

Green Lantern: First Flight (2009)
Directed by Lauren Montgomery

This movie is awesome! Animation quality is good, even great at moments (like the transformation).
So Hal Jordan inherits Abin Sur's ring, but when the Guardians find out Abin Sur's legacy has been handed down to a human they are displeased. Sinestro, a respected and feared Lantern suggests they give Hal Jordan a chance by letting the two work together for a bit. The Guardians agree.
After a short while of working together Hal Jordan sees that Sinestros methods for getting his man are all but humane. Sinestro even frames Hal Jordan for the death of the Corps' main suspect in the creation of a weapon as strong as the Green Lantern's battery. Sinestro has actually killed the suspect himself and is planning on finding and using the weapon. However because the Guardians believe Hal Jordan is responsible, they take from him the ring.
Big mistake, because Sinestro finds the weapon, essentially the same as the Green Lantern's battery but yellow. He swaps his green ring for a yellow one, then attacks the Corps.
Luckily Hal Jordan hadn't yet gotten sent back to Earth, because he find his ring and goes into the giant Lantern that houses the green battery. It seems that its dead from the attach from the yellow battery and it rains Green Lantern rings from the sky. All the Lanterns in space dies when the 'power went out'.
However, scratching the surface of the green battery reveals that under the dead outer coating, it's still alive inside. Hal Jordan holds his ring up to the battery while inside the giant lantern and becomes temporarily more super-powered that ever before.
With this new strength he takes out Sinestro and becomes the newest Green Lantern.

So when Hal Jordan transformed:

I did not make this youtube video, but it pretty much embodies how I felt about that sequence.
For the record though, this transformation sequence is totz boss. Love it.
Also, another nice touch to this movie was the choice to make Sinestro's teeth light yellow. Those little considerations add up to make a great animation.

Wow this one was weird. I'd put it in the weirdness of Allstar Superman. Not weird in a bad way. Just   weird.
If you're like me and have not read the comics, then this is a nice little view into a hand full of other Lanterns. I say it's weird because there's so many stories and flashbacks WITHIN stories, that you can easily forget something is just a tangent from the actual overall story.
Animation is pretty nice. Choice for voices is also enjoyable (Nathan Fillion of Serenity and Firefly, Jason Isaacs from Avatar: The Last Airbender, and Harry Potter, Elisabeth Moss from Girl, Interrupted, and other awesome talent).
I really really love that there's SO MANY character designs for humanoid and non-humanoid creatures. I mean I understand lots of bystander characters go into tons of animations, but usually they're all the same species as the main character(s). So lots of respect go out to the whole team that created and animated all the other worldly Lanterns.

So Hal Jordan has been trying to show rookie Arisia the ropes when evil strikes. Arisia has to go through trial by fire as Krona, in all his anti-matter villainy, enters through a sun to destroy the Green Lantern Corps.
During the wait period for Krona is when Hal Jordan and Sinestro tell Arisia all these stories of other Lanterns.
