“Pixels” (PG-13) 2 1/2 stars (out of four)

Adam Sandler and Kevin James take a byte out of their pasts as a pair nostalgic video arcade game nerds in “Pixels,” a visually-pleasing action comedy that will quickly make you forget the painful “Paul Blart: Mall Cop 2” from James, and about the last 10 movies from Sandler. It’s far from a perfect movie, but under the steady direction of Chris Columbus, “Pixels” is entertaining and nostalgic enough to more than pass as pleasing summer popcorn fare.

Sandler stars as Brenner, a home theater set-up man whose never quite been able to live down his loss in an arcade championship to video game hotshot Eddie (Peter Dinklage).While his life has gone sideways, his longtime friend, Cooper (James), has gone straight to the top as president of the United States. Still close with his arcade buddy, Cooper calls on Brenner and his expertise when aliens take the shape of 8-bit, ’80s video game characters and begin to attack different places throughout the world on their way to the nation’s capital.

A combination of “Wreck-It Ralph,” “Independence Day” and “Ghostbusters,” “Pixels” will be a huge trip down memory lane for arcade enthusiasts, as the pixilated characters from such video game creations as “Centipede,” “Pac-Man” and “Donkey Kong” come to life. Visually, it’s stunning, even if the story  gets sillier as the film goes along. It’s clear from the outset that “Pixels” isn’t supposed to be deep, just fun.

The best part about “Pixels” is its ensemble cast, as Sandler and James step back from their normal lead roles to let people like Dinklage and Josh Gad (as another one of their early ’80s video arcade buddies) do the heavy-lifting, comedy-wise. Gad is especially hilarious as a conspiracy theorist who has long lusted after Lady Lisa, the video game warrior babe of his dreams. Filling out the cast is the always sweet Michelle Monaghan as Violet, a single mom who holds a top military position at the White House, and her son, Matt Lintz as Matty, a pre-teen who takes an immediate liking to Brenner and roots for him to win his mom’s heart.

“Southpaw” (R) 3 stars (out of four)

Jake Gyllenhaal delivers a bruising performance in “Southpaw,” a gritty boxing drama that delivers some devastating blows, yet ultimately is a by-the-numbers “Rocky”-inspired sports movie that benefits from a stellar cast.

Gyllenhaal stars as Billy Hope, the undefeated light-heavyweight world champion whose career appears to be on the ropes as he emerges from his latest bout bloodied and battered. Taunted by a would-be challenger Miguel Escobar (Miguel Gomez) for a shot at the title, Billy’s hot-tempered response leads to a tragic personal loss; and before too long, his once charmed personal and professional life is a complete shambles.

Left destitute and suspended from the ring after an ill-advised comeback, Billy is literally left with nothing as his young daughter (Oona Laurence) is taken by child protective services and all of his assets are taken. Befriending  former trainer Tick Willis (Forrest Whitaker) at his small-time inner-city gym, Billy slowly rebuilds his life, personally and professionally, and with any luck, he’ll get a shot at his former glory.

Gyllenhaal is ferocious as Billy, and clearly put his all into physically and mentally transforming into the battered former champion. Apart from one wicked left hook in the narrative early on, the plot is hopelessly predictable; yet the energetic direction by Antoine Fuqua (“Training Day”) and inspired supporting performances by Whitaker, Laurence and Rachel McAdams (in a small but pivotal performance as Billy’s wife) contribute to the film’s big payoff.

“Paper Towns” (PG-13) 3 stars (out of four)

“The Fault in Our Stars” author John Green has scored another big-screen winner with “Paper Towns,” a poignant, coming-of-age dramedy that’s not quite as emotionally heavy as the teen cancer drama  starring Shailene Woodley and Ansel Elgort, yet is as emotionally satisfying.

Nat Wolff, one of the pivotal co-stars in “The Fault in Our Stars,” takes the lead role in “Paper Towns,” which chronicles the longtime friendship of  Quentin and Margo (Cara Delevingne) — a pair who bonded as youths but drifted apart as teens as Quentin stayed in his comfort zone and Margo’s free-spirited, adventurous ways grew. Literally strangers as their senior year draws to a close, Quentin and Margo — whom he instantly fell in love with the day they met — are oddly reunited, leading to Margo’s planned disappearance and her potential suitor’s search for her to reveal his true feelings for her.

Smartly scripted by “The Fault in Our Stars” scribes Scott Neustadter and Michael H. Weber, “Paper Towns,” while ultimately a coming of age dramedy, manages to avoid the trappings of most of today’s teen movie fare. It’s sweet, meaningful and poignant material, which is punctuated by terrific performances by Wolff and Delevingne, even though the latter’s screen time is limited. It’s also a road-trip movie with unpredictable results, which is refreshing in the world of the Hollywood retreads that populates today’s theaters.
