Green Lantern was fun while watching it, but after I dissected it, there were a large number of flaws, including the pacing. The pacing started out alright, then it meandered, then it got back on track, then it rushed the ending. And let's not forget some continuity snags and the character designs that I didn't care for and the usage of decent Lanterns as cannon fodder (Isamot Kol! WHY?!!)...
As for the CG, I expected it. Hell, I was okay with it for the constructs, as the other way I'd make those would be cell animation. Though Kilowog still had shifting weight maps. It's as if the entire budget went to Tomar-Re. He looked pretty decent. Kilowog, though...
