In-person acting and voice acting in animation are two different beasts, which is something that many actors who have worked in animation have attested to. Unlike live acting, voice actors receive very little help getting into character, and sometimes none at all, performing by themselves in a room.

Due to this, and many other circumstances, it is no wonder why some voice acting performances come across as lackluster. It can be easy to miss the amount of effort that goes into voice work and, because of this, it is important to acknowledge the cartoon shows where the voice acting is not just good, but at times exceptional.

The animated cast of Futurama

Futurama was a show that featured a strong cast of voice talent, such as John DiMaggio, Phil Lamarr, and Katey Sagal. The standouts in this cast, however, are Billy West and Maurice LaMarche who voice a significant number of characters on the show by themselves. Billy West voices the main character Philip Fry, as well as Professor Farnsworth, Zoidberg, and Zapp Brannigan with many others.

Meanwhile, Maurice LaMarche voices Kif Kroker, Donbot, and Calculon along with other voices as well. Each of these characters have such distinct voices that many people don't even realize they are voiced by the same people.

The voice cast also included Lauren Tom, who many may remember as the voice of Gizmo and Jinx in the original 2003 Teen Titans show.

Invader Zim is one of the most famous examples of gross-out humor in the 2000s. Everything about the show was bizarre and intentionally uncomfortable at times but simultaneously drew in the audience with its enigmatic performances. The title character, Zim, is voiced by Richard Steven Horvitz, who brings a ton of energy to Zim and making every one of his monologues worth listening to.

The show is a dark, brooding affair, but still includes a few moments of comedy, and each voice actor gives their character the weight and range that they need to sound believable in any given moment.

It makes sense that the characters are done so well since the cast has a lot of famous voice acting talent, including Christopher Sabat, Colleen Clinkenbeard, Sonny Strait, and Caitlin Glass.
