I know this a joke, but I actually agree.
The problem with Batman is that it's far too dark and serious for a character designed to sell comics and merchandise to children. The latest film was rated 15 in the UK making it unwatchable for many children who wanted to see it in the cinema, but there were some it wanted it to have a 18/R rating! That's ridiculous and I seriously side eye anybody who wants an adult Batman film.
Batman needs to go back to being light-hearted and family friendly. I'd be down for a full blown film reboot that mimics the Adam West TV series or at least Batman Forever.
