My parents normally dont like super hero films but my whole family really enjoyed it. I think an issue is that a lot of superhero films these days go in with the idea that you have already seen a shit ton of other movies beforehand or read the comics etc. But the superman film is pretty simple and just explains the barebones of his backstory to you while it tells the story. You don't have to have read a million comics to get what is happening or why what is happening is really important or something.
