I thought Sinestro's plot was a bit predictable but was executed very well to make you appreciate it. I knew somewhere in this movie he was gonna go black and yellow, And that design looked was better than the Green and Black.
Kilowog and Hal interaction was great. Kilowog is a hardcore Green Lantern patriot and only wants everyone but Hal to command the ring, him and the rest of the little blue guardians. Nobody likes humans because they smell but that changes by the end of the movie.
I loved that they included blood with every death. Boodikka death reminded me or spike ceiling in Mortal Kombat 2. This is what caught me off guard I didn't know she was a trader I thought it was Sinestro all a long.
The big show down at the end with Sinestro and the Green Lanterns was okay. I thought that they could at least tone down his power a bit to make the GL Corp fight a little more interesting, but whatever.
Sinestro is a really power hunger guy when his Yellow Lantern drained the Green Lantern of its power all the Green Lantern rings across the galaxy came back dropping like flies in front of GL corp guardians, without them they couldn't protect themselves they all died.
Hal was all green after taking the last remaining power of core Green Lantern rock after that him and Sinestro faced off. It was good even though Hal was doubled team he still managed to crush the yellow lantern.
