Sporting a flowing mullet and aviator shades, Dinklage perks things up considerably as the story’s comically arrogant bad-boy-turned-good-guy.

Pixels has a few inspired action sequences and a handful of laugh-out-loud moments, but overall the special effects are surprisingly average — and the lazy acting by Adam Sandler, the shameless mugging by Kevin James and the hammy performance by Brian Cox don’t help. Not even Peter Dinklage in a mullet can save the day.

At isolated moments a tolerably amusing send-up of alien invasion disaster movies in which the attackers are video arcade-era renegades arrived to gobble up as many famous landmarks as possible, this one-note comedy runs out of gas within an hour (it is based on a short film) and should have been trimmed to a neat 90 minutes.

The truly mystifying thing about the movie is how desperately it caters to Gen-X junk nostalgia without bothering to think that maybe those Reagan-era kids have grown up a bit.

The 3D adds little, and the hallmarks of the Chris Columbus directing style are unevenness and luck. With a little of the latter, this could be a huge hit. But with a better star, sharper script and more Dinklage, it could have been a champ.
