Dirty Grandpa (Unrated) | Full Movie | Movies Anywhere

I found these attempts at humor to be completely humorless, stunned that DeNiro or Efron would agree to be a part of this.

If you have a group of friends interested in a ridiculous comedy - or you have ingested copious amounts of booze and pills - you'll probably have a great time.

Incompetence combined with the occasional burst of disreputable laughter makes Dirty Grandpa oddly lively for a movie that's largely terrible.

I stopped expecting greatness from De Niro many moons ago. Why he feels he has to be out there in roles beneath himself is a mystery. But let's face it head on, he shows plenty of exuberance in Dirty Grandpa and it doesn't look like he'll be stopping.

There is one saving grace in Aubrey Plaza, of Parks and Recreation fame, who plays an incorrigible flirt. Otherwise, cold showers all round.
