Just watched it over the weekend. Not sure if Christopher Meloni was the best choice for Hal; and Michael Madsen as Kilowog? Nowhere near as good as Dennis Haysbert's work as him on Justice League. Victor Garber as Sinestro was the best (much better than Ted Levine as Sinestro from the JL days.) Tricia Helfer was solid as Boodikka.
By the numbers overall, but pretty entertaining. I was surprised to see it classified as PG-13 with the opening, but it proved to be right.
