GREEN LANTERN (Warner Bros. Pictures, 2011)

Directed by Martin Campbell; screenplay by Greg Berlanti, Michael Green, Marc Guggenheim, and Michael Goldenberg; 114 minutes; sci-fi/action-adventure; MPAA rating: PG-13 ("for intense sequences of sci-fi violence and action," but appropriate for ages 8 and up, if you ask me).

The longtime DC Comics superhero makes his big-screen debut in this special-effects extravaganza. Test pilot Hal Jordan knows how to fly a fighter jet better than almost anyone, but he's reckless and cocky, and can't shake the memory of watching his father die in a plane crash when Hal was just a boy. Millions of light years away, Abin Sur, a member of the intergalactic Green Lantern Corps (think of them as the space police), is mortally wounded fighting Parallax, a yellow mass of energy that turns out to be the physical embodiment of fear itself. Abin Sur crash-lands on Earth and gives his green power ring to Jordan, who is then indoctrinated into the Green Lantern Corps on their home planet of Oa and learns how to use his ring to create anything he can see in his mind, including giant machine guns and catapults. Jordan will have to overcome all his fear if he's to prevent Parallax from destroying humankind.

Green Lantern was considered a box office disappointment soon after it opened last June, and the critics weren't too kind, but I thought it was more entertaining than Thor, which came out a month earlier and did healthier business. All the money that went into the special effects budget appears to be on the screen, especially in the scenes set in outer space, and Parallax is a vaguely defined but impressive-looking villain. Reynolds isn't flexing any new muscles here in the acting department or otherwise, and after Robert Downey Jr.'s snarky portrayal of Tony Stark in two Iron Man movies, Reynolds's similar approach demonstrates the law of diminishing returns. (Peter Sarsgaard, as pseudovillain Hector Hammond, seems to be having the most fun out of all the actors.)
