"That's My Boy" might be the funniest Adam Sandler comedy in a decade, but audiences wouldn't know: the R-rated laugher earned just $4.6 million on Friday night, putting on track to earn just $13 million through the weekend. That would give Sandler his worst opening weekend since "Reign Over Me" in 2007, and his worst for a live-action Happy Madison-production since "Little Nicky" in 2000.

Things weren't much better for Tom Cruise. "Rock of Ages," which features a flamboyant and all-in performance from Cruise, grossed $5.35 million on Friday night. Based on that start, the musical could total around $15 million for the three-day weekend, which would put it behind holdovers "Madagascar 3" and "Prometheus."

Ridley Scott's much-discussed R-rated thriller pulled down $5.8 million on Friday and could gross almost $20 million by Sunday night. That number would represent a nearly 60 percent drop from last weekend's $51 million opening, meaning word of mouth on "Prometheus" isn't as strong as Scott and studio Twentieth Century Fox would have liked.

As for "Madagascar 3," the film grossed over $10 million on Friday night. The Paramount release could have an addition $35 million in its coffers by Sunday.

  • Ty Burr (Boston Globe)

    "Rock of Ages" is exuberant, silly, overlong, sexist; <a href="http://www.boston.com/ae/movies/articles/2012/06/15/rock_of_ages_review_tom_cruise_takes_on_axl_rose/?rss_id=Boston.com+--+Movie+news" target="_hplink">it's clever in little matters and proudly dumb in the things that should count</a>.

  • Roger Ebert (Chicago Sun-Times)

    The actors are having a lot of fun, <a href="http://rogerebert.suntimes.com/apps/pbcs.dll/article?AID=/20120613/REVIEWS/120619993" target="_hplink">and the production values of the musical numbers are slick and high-spirited</a>.

  • Andrew O'Hehir (Salon)

    "Rock of Ages" is an effulgent celebration of fakeness. It isn't trying to be real; <a href="http://www.salon.com/2012/06/13/rock_of_ages_the_joys_of_total_fakeness/" target="_hplink">it's trying to be faker than any fake thing has ever been before</a>.

  • Owen Gleiberman (Entertainment Weekly)

    Most of the numbers in Rock of Ages are flatly shot and choreographed, and they look as if they'd been edited together with a meat cleaver. With rare exceptions, <a href="http://www.ew.com/ew/article/0,,20483133_20587889,00.html" target="_hplink">they don't channel the excitement of the music - they stultify it</a>.

  • Nathan Rabin (AV Club)

    A shameless crowd-pleaser where cardboard characters use the most overplayed and <a href="http://www.avclub.com/articles/rock-of-ages,81230/" target="_hplink">ubiquitous hits of the 1980s to express the aching banality of their souls</a>.

  • Guy Lodge (Time Out)

    As with Shankman's knowingly naff 'Hairspray', <a href="http://www.timeout.com/film/reviews/91639/rock_of_ages.html" target="_hplink">the sheer performance gusto on display proves thoroughly winning</a>.

  • Olly Richards (Empire Magazine)

    Like every one of its songs, it makes a lot of noise about nothing much and cockily straddles awfulness and greatness. <a href="http://www.empireonline.com/reviews/ReviewComplete.asp?FID=135940" target="_hplink">It's enormously entertaining nonsense</a>.

  • Nick Schager (Slant Magazine)

    If the Adam Shankman film's debasement of its subject into campy kitsch is the unavoidable fate of all culturally dangerous art, <a href="http://www.slantmagazine.com/film/review/rock-of-ages/6344" target="_hplink">that doesn't make it any less palatable</a>.

  • Justin Chang (Variety)

    Given the proliferation of high-school musicals and American idols on TV, <a href="http://www.variety.com/review/VE1117947727?refcatid=31" target="_hplink">the spectacle of aspiring young singers belting out an umpteenth cover of Journey offers little in the way of novelty value</a>.

  • David Rooney (Hollywood Reporter)

    [Shankman] succeeds in draining most of the fun from a vehicle <a href="http://www.hollywoodreporter.com/review/rock-ages-review-tom-cruise-335511" target="_hplink">that was all about the winking humor of its flagrant cheesiness</a>.
