The premise has potential, but the execution is painfully unfunny.

| Original Score: 2/5 | Jun 8, 2021

The kind of film that, one day, De Niro's great-grandchildren will watch and wonder what all the fuss about him was.

| Original Score: 1/5 | Feb 3, 2021

Mazer can't decide what kind of film Dirty Grandpa is to be.

| Original Score: 1.0/4.0 | Sep 6, 2020

De Niro's legacy as an actor will be cemented with ground breaking films like Casino, Raging Bull, Taxi Driver, Goodfellas and Heat - just to name a few. Dirty Grandpa will not.

| Original Score: 1/5 | Jul 17, 2020

Dirty Grandpa had potential to be a good gross-out comedy, but it's mostly just gross.

| Original Score: 2/5 | Apr 9, 2019

DIRTY GRANDPA is nothing more than an exercise in wink-and-nudge boorishness that leaves a bad taste in your mouth.

| Original Score: F | Mar 30, 2019

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

| Original Score: F | Jan 17, 2019

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.

| Original Score: 4/10 | Oct 25, 2018

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

| Original Score: C- | Sep 14, 2018

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.

| Original Score: 2/5 | Aug 22, 2018

The extent of the plot is literally just Robert De Niro wanting to f*** a college girl (who is of course depicted as an unabashed s***), because after 40 years of being faithful to his recently deceased wife, he feels entitled to some fun...

| Original Score: 2/5 | Dec 4, 2017

The fun of sex is the entire point of the raunchy, goofy Dirty Grandpa. You have to be humorless (and sex-averse) to be offended by its deliberate naughtiness as so many critics have demonstrated.

| Mar 3, 2017

The un-ironic title is like a spray-painted graffiti sign warning everyone to stay away from this sewage-swilling clogged cesspit masquerading as a movie.

| Original Score: 1.5/5 | Jan 11, 2017

Equal parts bad and baffling, it seems to have been written and directed by alien life forms who read YouTube comment sections for a week and drew these conclusions about human behavior.

| Jul 23, 2016

A burlesque like Dirty Grandpa means to "liberate the oppressed" and does so in a low-comedy way. Ignore the bluenose critics who sharpened their dentures on this movie; ironically, they're the same fools who swallow drivel like The Hunger Games.

| Jun 27, 2016

No matter how many brief yucks you get out of Plaza's sledge hammer advances or De Niro attempting the kind of fast talking sex talk; you feel desperation.

| Original Score: 1/5 | Jun 21, 2016

Pure comedy sewage.

| May 31, 2016

A movie so annoying, so ugly, so lead-footed, so misguided, and so blisteringly unfunny it has to be seen to be believed. Please don't see it, though. It's not worth the sacrifice.

| Original Score: 0/4 | May 17, 2016

Though there are some polite, heartfelt moments about living life to the full, Dirty Grandpa is an arrangement of outrageous lines and sight gags for those who like their comedy crude, if somewhat pointless.

| Original Score: 2/5 | May 16, 2016
