When CGI and 2D Animation Mix Like Oil and Water (But Hollywood Forces It Anyway)

When CGI and 2D Animation Mix Like Oil and Water (But Hollywood Forces It Anyway)

There’s bad animation, and then there’s whatever this is.

For decades, studios have been obsessed with shoving CGI and 2D together, even though it almost never works. Sometimes, it’s an artistic experiment. Other times, it’s a budget-saving shortcut disguised as a creative choice. And sometimes? It’s an unholy crime against animation.

So today, we’re roasting the worst, most painful, most Frankenstein-like attempts at mixing CGI and 2D animation.

⸻

10. The Road Runner Segments in The Looney Tunes Show (2011-2014) – AKA “Why Does the Road Runner Look Like a Video Game NPC?”

The Crime:

• The main show is fully 2D, but for some reason, the Road Runner shorts are full CGI.

• The Looney Tunes have always been about hand-drawn slapstick. So naturally, they thought, “You know what these classic cartoon characters need? Plastic textures and motion blur.”

• It’s like watching a PlayStation 2 cutscene spliced into a normal episode.

Why It’s a Disaster:

• CGI Wile E. Coyote moves too smoothly, killing the classic slapstick feel.

• The backgrounds are pre-rendered CGI nightmares.

• It feels like watching two different cartoons stitched together.

Verdict: The Road Runner is fast, but he should’ve run FAR away from CGI.

⸻

9. The Lion Guard (2016-2019) – AKA “2D Lions Lost in a CGI Wasteland”

The Crime:

• The Lion King is one of the greatest 2D animated films ever. So naturally, Disney made a spin-off series where the characters are 2D, but the backgrounds are ugly, blocky CGI.

• The lighting never matches. The characters look pasted onto a different dimension.

Why It’s a Disaster:

• The backgrounds feel like something from a cheap mobile game.

• The CGI environments lack depth and texture.

• The characters look like they’re floating instead of standing on solid ground.

Verdict: The Circle of Life just got broken.

⸻

8. Rugrats: All Grown Up! Opening Credits – AKA “Stretch Armstrong Babies”

The Crime:

• Rugrats was always 2D. Then All Grown Up! decided, “Hey, let’s add 3D elements for no reason.”

• The opening credits use CGI camera movements that stretch and warp the 2D characters in horrifying ways.

Why It’s a Disaster:

• The characters’ heads distort like they’re in a funhouse mirror.

• CGI effects are used purely for the sake of it, with no logic.

• It looks like a bad After Effects tutorial from 2003.

Verdict: Nobody asked for CGI Rugrats. Nobody.

⸻

7. Beauty and the Beast Ballroom Scene (1991) – AKA “PlayStation 1 Backgrounds in a Disney Movie”

The Crime:

• The first-ever use of CGI in a Disney feature film… and it shows.

• The ballroom was rendered in 3D, but Belle and the Beast are 2D.

• The camera movements feel way too floaty, like they’re dancing in a dream sequence.

Why It’s a Disaster:

• Groundbreaking in 1991. Unsettling now.

• The CGI background doesn’t blend with the hand-drawn animation.

• It’s like watching two different art styles fight for dominance.

Verdict: It was impressive in its time, but now it just looks cursed.

⸻

6. SpongeBob SquarePants (2010s-Present) – AKA “Bouncy CGI Creepiness”

The Crime:

• SpongeBob was always 2D. But as the years went on, CGI effects started creeping in.

• Characters became extra bouncy, gelatinous, and oddly shiny.

Why It’s a Disaster:

• Some episodes have CGI elements that look weirdly out of place.

• The ultra-smooth movement removes the charm of classic SpongeBob.

• Backgrounds sometimes switch to hyper-detailed CGI, making SpongeBob himself look like he’s lost in a different world.

Verdict: Just because you can add CGI doesn’t mean you should.

⸻

5. Tarzan (1999) – AKA “Tree Surfing on a Green Screen”

The Crime:

• Tarzan’s “Deep Canvas” technique was revolutionary… but also weird as hell.

• The trees are 3D, but Tarzan is still 2D, making him look like he’s sliding instead of running.

Why It’s a Disaster:

• The CGI trees look too smooth and fake.

• Tarzan’s movement doesn’t blend with the environment.

• The physics make no sense—he’s surfing on branches like he’s on a Tony Hawk level.

Verdict: Cool idea, but it aged like milk.

⸻

4. Clifford’s Really Big Movie (2004) – AKA “Weird CGI Shadows That Nobody Wanted”

The Crime:

• They took Clifford, a perfectly fine 2D cartoon, and added creepy CGI shading to everything.

• The result? Greasy, plastic-looking characters.

Why It’s a Disaster:

• The CGI shading makes the characters look like melted crayons.

• The backgrounds are weirdly 3D while the characters remain flat.

• It looks like a bad Flash animation mixed with a PlayStation 2 game.

Verdict: Some things should stay simple.

⸻

3. The SpongeBob Movie: Sponge Out of Water (2015) – AKA “Why Is SpongeBob a Wax Figure?”

The Crime:

• The first half of the movie is classic 2D. Then, suddenly, SpongeBob becomes a horrifying 3D CGI character.

• The 3D models have too much texture, making them look rubbery and dead inside.

Why It’s a Disaster:

• CGI SpongeBob is nightmare fuel.

• His movements are too smooth, making him feel like a puppet.

• It loses all the charm of traditional SpongeBob.

Verdict: Just keep him in 2D, for the love of all that is holy.

⸻

2. The Smurfs (2011) – AKA “Why Did This Movie Happen?”

The Crime:

• The Smurfs are CGI. The humans are real. Everything is pain.

• Every Smurf looks like a blue balloon animal.

Why It’s a Disaster:

• The CGI Smurfs have a weird, glossy texture.

• Their movement is too smooth, making them feel disconnected from the world.

• It’s just an excuse to put CGI Smurfs in live-action New York.

Verdict: A Smurfing mistake.

⸻

1. Tom & Jerry: The Movie (2021) – AKA “CGI Purgatory”

The Crime:

• Tom and Jerry are CGI, but everything else is real.

• They tried to make them look 2D, but it just doesn’t work.

Why It’s a Disaster:

• CGI Tom and Jerry look like unfinished test footage.

• Their physics don’t match the real world.

• The charm of the originals is completely lost.

Verdict: Just watch classic Tom & Jerry. This never happened.

⸻

Final Thoughts: STOP DOING THIS.

Whenever 2D and CGI animation mix, it’s usually a crime against animation. Some styles just aren’t meant to blend.
