I think all Christians should watch The Good Place. It does a great job showing why the most Christian concepts of heaven and hell aren't ethically sound.
It is a hilarious show that is also like a really great introductory ethics class. It sounds weird, but it works.
It pokes fun at a lot of ethical viewpoints. It shows the short comings deontological (lawful good, follow the rules) several times even though one of the main characters loves Kant. Christian ethics is pretty much deontological, but inconsistent and impossible to actually follow to a T.
I also think it is probably the best series of all time. At least the best I have seen. It is loaded with references, foreshadowing, details and subtleties. I have seen the whole thing 4-5 times and notice new things every time.
