Throughout its run, the series earned critical acclaim from Time, National Review, Rolling Stone, Newsday, The New York Times, The New Yorker, the San Francisco Chronicle, the Chicago Tribune, and Entertainment Weekly.
Diane Werts of Newsday wrote: "You can look at this saga any way you want—as political drama, religious debate, psychological suspenser, sci-fi adventure, deep metaphor or just plain fun—and it's scintillating from every angle." Robert Bianco of USA Today commented: "Driven by violence and rage, Galactica is perhaps the darkest space opera American TV has ever produced. In Galactica's future, humans are on the run, and if external enemies don't get us, internal divisions will... You'll understand them [the characters], their conflicts and their desires, because they're recognizable humans in all their glorious complexity. And that's what makes Galactica a great TV series."[42] Peter Suderman of National Review stated that the series is "arguably the most potent, dramatically vibrant series on television. ...t packs the power of a gut punch on screen. For that, much credit is due to the immensely compelling cast of characters... Battlestar Galactica burns with a combustive mixture of political turmoil and human drama that is as achingly real and relevant as anything on television.Jeff Jensen of Entertainment Weekly wrote that the show "has distinguished itself as one of television's very best dramas — on a par with 24, The Wire, and Lost — because it so utterly transcends both its genre and its source material. ...[The] series' sophisticated stories have also attracted a distinctively new breed of fan, one who's not necessarily a sci-fi buff."
Mary McNamara of the Los Angeles Times praises the show's ability to "anchor fantasy with vivid and recognizable human psychology" and declares that the series is "not just a cult hit but a significant piece of television." Maureen Ryan of the Chicago Tribune describes it as a "sprawling, enthralling tale of human survival" that is "full of political allegories and fascinating, multifaceted characters." She finds, "Like Deadwood, Battlestar Galactica is interested in exploring how a society on the edge decides to govern itself. What rights and actions are sacrosanct, which are outlawed, when most of the human race is eliminated? ... Thanks to a stellar cast and brave writing, Battlestar soars." Throughout its run, the series has often surprised reviewers with its many twists and turns. Ryan comments: "There’s nothing like a good Battlestar plot twist to make your head spin, but the “holy cow” moments aren’t the main point (though they’re one heck of a tasty side dish). The show and its twists and turns are grounded in deep curiosity about human nature, and how contradictory and confounding it can be."
Matt Soergel of The Florida Times-Union states: "Its propulsive and complex storytelling is matched by, at best, just a handful of theatrical movies a year." Tim Goodman of the San Francisco Chronicle opines, "Battlestar Galactica transcends the sci-fi genre; it competes, creatively, on the same level as any other top-tier drama." Mark Perigard of the Boston Herald states: "A drama this gripping comes ’round rarely."[52] James Poniewozik of Time Magazine named it one of the 100 best TV shows of all time. Time magazine also wrote in the spring of 2005 that the new show was one of the six best drama programs on television. It would proclaim the program the best show on television in December of the same year. Television Without Pity describes Battlestar Galactica as "one of the finest, most beautifully written, expertly acted shows on television."[54] Alan Sepinwall of The Star-Ledger writes: "[W]hat makes Galactica so gripping is its emphasis on character over hardware. The explosions and the killer robots are cool, but they don't stack up to seeing fully-drawn people - brought to life by a great writing staff led by producer Ron Moore and an astonishing cast led by Edward James Olmos and Mary McDonnell - grapple with these life-or-death, genocide-level decisions." Joshua Alston of Newsweek declares that the show "captures better than any other TV drama of the past eight years the fear, uncertainty and moral ambiguity of the post-9/11 world" and "always finds ways to challenge the audience's beliefs."
The series also draws praise for having many strong and complex female characters. The Seattle Post-Intelligencer's Melanie McFarland notes, "[Starbuck], played with a tomboyish swagger by Katee Sackhoff, is fast becoming the latest in a long line of feminist television icons."
The series has also received favorable reviews from other writers. Stephen King wrote, "This is a beautifully written show, driven by character rather than effects...but the effects are damn good. And there's not a better acting troupe at work on television." Joss Whedon commented: "I think it's so passionate, textured, complex, subversive and challenging that it dwarfs everything on TV."
