PHOTOS: Zac Efron’s Bare Booty Is The Only Compelling Part Of “Dirty Grandpa”

We could try to tell you about the movie Dirty Grandpa, starring Zac Efron and Robert De Niro, but Rotten Tomatoes does a far better job at summing up the flick than we could ever hope to accomplish:

Like a Werther’s Original dropped down a sewer drain, Dirty Grandpa represents the careless fumbling of a classic talent that once brought pleasure to millions.

Yikes. And we thought Stonewall sounded bad.

But at least one redeeming thing can be said of the film — it offers some unobstructed views of Zac’s genetically perfect backside.

That’s a silver lining we can get behind.

While it won’t actually make us watch the film, we salute this last ditch effort at appealing to the masses.

Head here for some NSFW GIFs of Zac’s booty. It’s called art.
