"Batman v Superman: Dawn of Justice" is facing a rocky start ahead of its Friday release. The tentpole has met with lukewarm reviews and holds a bleak Rotten Tomatoes percentage (which continues to change as more reviews roll in). The last installments fared far better for these caped crusaders, with "Man of Steel" holding a 56% Fresh rating and "The Dark Knight Rises" holding a Fresh 87%.

Although there are a few positive reviews for Zack Snyder's film, most are calling out the film for its messy, less-than-spectacular promised clash of comic-book titans.

Variety's Andrew Barker says this epic standoff never develops fully, and instead "the life-or-death battle between the two icons ultimately comes down to a series of misunderstandings." Barker also believes Henry Cavill's Superman pales in comparison to "the winningly cranky, charismatic presence even when out of costume" of Ben Affleck's Batman. Visually, the film is a win.

Eric Kohn of Indiewire echoes some of Barker's points by calling this messy and "cacophonous" showdown "basically one long teaser for the next installment." Kohn also pointed out that while the film "doesn't lack for inspired visuals" because "it's filled with motion-heavy sequences rich in light and color," a good deal of the story "reeks of the usual routine."

Peter Travers of Rolling Stone thought this was a step up from "Man of Steel" but nowhere near Christopher Nolan's "Dark Knight" franchise. However, even though "Batman v Superman" is probably a dream for most comic-book fans, the "kick-ass revelation" is the "wowza of a Wonder Woman," played by Gal Gadot.

But Todd McCarthy of the Hollywood Reporter believes the writers threw in the towel on how to integrate Wonder Woman. "With just her sword and shield, she doesn't seem meant to mix it up with these big guys right off the bat," he writes. McCarthy also adds that the lead characters are not fully developed, but may be in the next installments.
