The latest trailer for Green Lantern may very well be the best argument against the shrinking number of naysayers for this film. While it's (apparently) in 3D, the selling point is the presentation, which is absolutely epic.
By now, you've certainly seen more than your fair share of Green Lantern, with trailers airing on television and the merchandise and toys are starting to flow on the pegs of retail stores everywhere. (Movie Masters Hal Jordan action figure ftw.) However, I think it's pretty safe to say that we've never seen the storyline, which on paper is too complex and unworkable for a movie, explained so eloquently as by Geoffrey Rush's Tomar-Re, aided by the powerful (apparently 3D) visual effects.
From explaining the origin of the Emerald Energy of Willpower to the looming threat of Parallax, powered by the Yellow Power of Fear (which also foreshadows the future plans of Mark Strong's Sinestro,) this trailer pretty much cements the film as a must-see when it hits theaters on June 17.
