The gypsy curse is a major plot point that never goes away. Even when most of that storyline is dealt with, it’s still brought up again and again.
Apart from Buffy having sex completely unbeknownst to her mum, you have the love of her life turning into a nightmare after she sleeps with him. If you’re ready to have a conversation about sex and abusive relationships… go for it. And again with Spike… someone who Buffy trusts, and who she should in theory be strong enough to fight off…
Joyce’s sudden death - probably even harder to watch if your child only has one parent. The supernatural deaths won’t register, but losing a parent… the only one actually in Buffy’s life… that’s heavy.
Willow’s seemingly sudden change in sexuality?
Xander emotionally neglecting and mistreating Anya?
The acceptability of adopting some random man in tweed as a pseudo parent figure?
I enjoyed watching Buffy, but ignoring the problematic aspects of certain people involved in the show… there are a lot of big conversations required. It depends on how emotionally mature your child is, and if you’re ready to take away their innocence.
There are so many unhealthy relationships to discuss and you need to explain why no one should put up with them in real life.
