Okay, so I'm about to totally rail on _Batman Ninja_, but before I do that, I wanted to open it up with the following disclaimer: I thought multiple times throughout watching this "I wonder if this could be the sort of thing that's fun if you watched it in a group setting?". Personally, I watched it by myself, on a bad day, bedridden, feeling very, very unwell. And that's the experience I'm reviewing. Movies don't have to be grounded to be good. They don't have to be be standardised to be good. They don't even have to make sense to be good. Sometimes a movie is just silly fun and everything...
