Common Sense Note
Parents need to know that this cartoon derives from a Marvel comic book steeped in occult magic and mysticism, and sorcery that impinges on the real world (as opposed to fairy tales). It's wildly fantastical and not quite as campy as the comics (none of Stan Lee's nonsensical invocations such as "By the hoary hosts of Haggoth!"). There is also some creepy imagery, especially involving bewitched and zombie-like children. One attempted suicide.
Some female warriors wear skimpy bikini tops (always what you need battling monsters, of course).
Sympathetic characters are killed, and others stripped to skeletons in magical combat. The main character is maimed (non explicitly) in a car wreck.
There is a contrast between Strange, who gets to be become Sorcerer Supreme, and the seemingly more-qualified Mordo, who only cares about victory and not the safety of his comrades. Maybe Strange's background as a physician is meant to symbolize his altruism, but he's a pretty cold doctor. Before he gets enlightenment/superpowers the hero attempts suicide.
The promotional tie-in with the comic-book series is hard to overlook.
