Movies that shows Animation isn't just for Kids

Oh my god! All I'm going to say that this is one of the most depressing movies I ever saw and this made me cried multiple times.

The dark themes, religious themes and not to mention "Hellfire".

This features cats being brutal murdered, the main character having strange nightmares, and an scene where two cats did it.

This one nails what life was during the time people thought of America as a really great place but in reality, it is rough living there. Not to mention this has an depressing feel to it as Fievel looks everywhere for his family nearly almost getting killed many times.

Same reason like the the first one above.

This shows that animation can be much more than be a feature or short and can create alot of possibles.

Kind of like Black Swan in a way.

Do I need to explain about this one.

While having a simple plot, it works well due to the execution of the plot, the main leads are relatable, and the animation have a lot of details and emotion that makes everything work. Most of all, it never insults it's audience.
