I liked it, it sucked compared to Thor, the G said, the story was done terribly, they just tried to cram too much info and back story into too short a time IMHO, and the other Lanters were in it for like 2 fucking seconds...
Sinestro comes out to tell everyone how they face an "unprecedented danger" and they have to forge the yellow ring, but then Hal defeats the whole thing on his own, easily, while the other lanters sat around with their thumbs up their asses. Just bad storytelling all over the place.
BUT, I thought they did a good job with the characters, the effects were cool... just sucks they had so much to work with and it was so anticlamactic.
