It's also best known in particular for working on animation of Western animated shows like DuckTales, Batman: The Animated Series, Animaniacs, Tiny Toon Adventures, Superman: The Animated Series, Iznogoud, The New Adventures of Zorro, Adventures of the Galaxy Rangers, some episodes of Transformers G1, Visionaries: Knights of the Magical Light and early cartoons created by DiC Entertainment.

This is why, this anime studio DOES western animation!

They do an excellent job with their animation, for it's inspired many animation studios.

They have also worked on the animation of some western animated movies as well, like Little Nemo: Adventures in Slumberland (despite a box office failure), Tiny Toon Adventures: How I Spent My Vacation, Animaniacs: Wakko's Wish, and Batman Beyond: Return of the Joker.

They put in excellent music for the anime they create.

They even put full episodes of their shows on their official YouTube channel for free, albeit dubbed.

Bad Qualities
Some of their works are less than stellar animation wise such as Spider-Man: The Animated Series.

Some of anime shows are bad, mediocre, average, disgusting, unfaithful, unlikable, overrated and forgettable, such as Ohayo Spank, The Rose of Versailles and Lady Georgie.

Unlike Toei Animation, TMS Entertainment has the shows with gross animation at times.

Many of their shows have episodes who has too bad impact.
