While 3-D makes sense for the splashy adventures of Spider-Man, the trend could spell doom for the gritty, realistic world of Batman. Let's take a look at how 3-D could positively (and negatively) affect some upcoming comic-book-movie releases.

Next May, the Mighty Thor will be the first Marvel hero to battle evil in 3-D. (Though Superman Returns got the Imax treatment at select theaters, back in 2006.) The 3-D technology could be just what director Kenneth Branagh needs to bring Asgard to life. From Odin's palace to the rainbow bridge that connects the Earth to Asgard, the world of Thor is simply begging to be seen in more than two dimensions. (Besides, anyone worried about realism should pick up some Thor comics -- there's a lot of crazy stuff going on.)

No speculating here: Warner Brothers has already confirmed that Ryan Reynolds will be wielding the Green Lantern ring in 3-D. As with Thor, 3-D could help Hal Jordan's chances at the box office. Fans will want to see all sorts of eye-popping creations from Green Lantern's ring, which can do whatever the wearer imagines. (Not to mention that the recently unveiled CGI costume will pop in 3-D.) Superhero cops battling aliens is exactly the sort of big-screen spectacle 3-D was made for.

While Marvel's Thor plans make sense, having Captain America punch out Nazis in 3-D smacks of bandwagon jumping. Cap's origin story should be a straightforward World War II tale, not an eye-popping extravaganza. (Outside of Cap's shield, what else could possibly leap from the screen? Bucky Barnes tossing liberty cabbage at Red Skull?) Meanwhile, director Joe Johnston is also wary, calling 3-D "overused" and "gimmicky" in the pages of the Los Angeles Times.

With its cast in place (word is Kevin Bacon will play villain Sebastian Shaw), Matthew Vaughn's X prequel is all but guaranteed to get a 3-D makeover. After petering out with the flat X-Men: The Last Stand, the franchise could use a visual boost to get it back on track. We've yet to see Cyclops's optical blasts in 3-D, and with new mutants like Banshee and White Queen onboard the potential for nifty special effects has increased. Plus, getting a face full of Wolverine's claws could be pretty intense.

With news that the third Bat flick will commence production in April, fans are already speculating whether director Christopher Nolan will take the Caped Crusader into the third dimension. Considering that a follow-up to The Dark Knight is basically a license to print money, it's safe to say that DC Comics and Warner Brothers will push for 3-D, in an effort to inflate ticket prices. Word has it that Nolan would rather shoot entirely in Imax, in order to retain the epic look of his previous Batman outings. Here's hoping the great director sticks to his guns.
