Sahara

The animation here is decent and the voice acting is mainly good.

HOWEVER

This is a film about a watermelon-eating cobra teaming up with a substance-abusing green snake to rescue another green snake from a racist caricature. There is a lot that this film gets wrong factually. Some can be attributed to artistic license, but a lot is just laziness. There are also some extremely questionable artistic decisions, such as the aforementioned stoner snake in a children's film, which leads to scenes in which he gets high, and snorts sand in the desert like cocaine. While most of the character design is good, there are a couple of notable exceptions where the character looks disgusting, or where they have clearly copied a character from elsewhere. The plot is okay, but a lot of it feels recycled from previous films, including some extremely cliched set-pieces.

In general, this is not the worst animated film ever. That does not make it good. I'd say put it on for a child then leave the room, but that would teach them that quality does not matter in children's films. Also, the drugs-based humour probably needs a responsible adult to put into context for them. Instead, put on a good film for your child, like Shrek or Chicken Run.
