Even then, it generally requires a ton of money and meticulous effort to look believable and immersive.

As a result, there are plenty of movies out therewith atrocious CGI.

With this in mind, this list looks at some of the most egregious offenders.

The Thing

In some cases, shoddy graphics undermined the whole movie.

Given the $15m budget, Mama should have been way scarier.

Still, the movie was a massive hit,bringing ina whopping $148m.

Needless to say, this approach did not go down well with fans.

There are a few scenes here where the shapeshifter looks truly abysmal; somehow both boring and fake.

Some of the shots of the character’s capes also look ridiculously, plasticky and unrealistic.

How hard is it to animate a cape?

The budget was $300m!

The aliens look awful, landing awkwardly between serious and cheesy.

It’s hard to tell if they’re meant to be a joke or not.

There’s a reason few people even talk about this movie these days.

It’s rough when you’re being outclassed by the likes ofWerewolves WithinandJumanji.

DC strikes again withGreen Lantern.

The movie leans heavily on its graphics, many of which are lame and undercooked.

The hero’s costume, in particular, looks unignorably bad.

The 3D didn’t help matters, making the weak CGI even more noticeable - and distracting.

Many viewers and critics ridiculed the graphics, particularly the bizarro look of the Cullens' baby.

Renesmee isveryunsettling, more like something out of a horror movie.

Believe it or not, this was actually the revised version of the character.

The original’s appearance was reportedly way worse.

Unfortunately,over-the-top digital kill scenes and generally weak effects make this movie more disposable than disturbing.

Some of the computer-generated shots of Freddie coming through walls are complete duds.

The original movie used Spandex to achieve the same make with more realism and at less cost.

It goes to show that ingenuity often trumps money when it comes to immersive visuals.

This disaster flick fully embraces its absurd premise of tornadoes filled with ravenous sharks wreaking havoc on Los Angeles.

Still,this is precisely its charm and whySharknadobecame a cult movie.

Unfortunately, the overly self-conscious sequels offered diminishing returns.

WhileSharknado’s trashy CGI was ironically enjoyable, the bad visuals inCatsonly make the movie worse.

The characters are ‘uncanny valley’ hybrids of human and feline, with unsettling faces and creepy bodies.

Their sizes are also inconsistent, and they clash with the similarly low-quality environments around them.

It remains one of the most derided films of the 2010s.

It would’ve been shocking in 1960, let alone 2010.

The writing and performances are little better, makingBirdemica true icon of awfulness.
