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

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

This is a movie that desperately wants to be a raunchy, politically incorrect, gross-out comedy. It gets as far as desperate.

| Feb 4, 2016

Its horrible message: the old are only interesting when they're capable of aping the young.

| Original Score: 1/5 | Jan 31, 2016

Steer away from Dirty Grandpa, just as you would sidestep a dog turd on the pavement.

| Original Score: 1/5 | Jan 31, 2016

Plays like one of those dire mainstream films that - thanks to a few extreme moments - Quentin Tarantino periodically reclaims in his best-of-the-year list.

| Original Score: 2/5 | Jan 30, 2016

Nothing is rendered in a particularly funny or novel way - it's just crude, shocking statements. Therefore, the film isn't actually offensive because it's trying so hard to be and failing miserably.

| Jan 29, 2016

Be ashamed, Robert De Niro, be deeply ashamed of every scene of Dirty Grandpa, a sleazy comedy spurting unfunny jokes from a lost time.

| Original Score: 0/5 | Jan 28, 2016

There are a few moments of hilarity, but most of the film seems merely grotesque. It's baffling as to what draws De Niro to such material when he should be playing Willy Loman or King Lear.

| Original Score: 2/5 | Jan 28, 2016

A sad and, in the end, utterly sappy affair that recycles the same checklist of tropes that lulls audiences into thinking they are watching an edgy comedy.

| Original Score: 0/5 | Jan 28, 2016

This grossout comedy takes De Niro fans into a new emotional phase that I can only call "post-despair". We are past being astonished and horrified.

| Original Score: 2/5 | Jan 28, 2016

The ugliest film in recent memory - in every sense of the word - we can only hope it meets the fate it deserves.

| Original Score: 1/5 | Jan 28, 2016

There's something dated about the script, graspingly keen to be edgy but often wearyingly outmoded - are we honestly still treating gay euphemisms as a bottomless well of hilarity?

| Original Score: 2/5 | Jan 28, 2016

This is the most engaged De Niro performance in at least five years: his dialogue is both apocalyptically unfunny and clearly enunciated, which somehow makes it all the more galling.

| Original Score: 1/5 | Jan 28, 2016

Tinged with the sadness of watching a beloved elderly relative making a bloody old fool of himself.

| Original Score: 2/5 | Jan 25, 2016

"Dirty Grandpa" is like watching a friend's mediocre improv troupe do an extended spring-break sketch. And your friend just happens to be Robert De Niro.

| Jan 23, 2016

Crude in nearly every sense of the word, "Dirty Grandpa" is a nasty-humored, poorly made and desperately unfunny film.

| Jan 23, 2016

You gotta give De Niro a hand (and a maybe a tissue) for the way he dives right into this role. He chews through the icky dialogue and even lends the character some warmth in the process. The movie doesn't deserve it.

Full Review | Original Score: 1/5 | Jan 22, 2016

It will make you feel bad for yourself, and anyone else who sees it, and anyone else who has to live in the world where it exists as a physical document.

| Original Score: D- | Jan 22, 2016

If Dirty Grandpa does anything, it should be to make you stop weeping for De Niro's lost greatness. He brought this upon himself.

| Original Score: 1/4 | Jan 22, 2016
