Cool idea, and different, but not something I'd probably recommend to most Batman fans.

It's basically Batman dealing with a crazy cult, as the title says. It starts off simple enough, Batman is captured, they torture him some, and he joins them. However, soon into the book he breaks free of the trance but not fully. Thanks to the city under hell, Robin, and his determination, it's up to Batman to make it out alive and save everyone.

Good: Surprised how dark it got, but never too cheesy. The deaths are brutal and the cursing too me by surprise, but they work for the tone and style. I also thought Batman struggling throughout was a nice change and different.

Bad: The dialogue can be really really outdated, making it hard to take serious at times. I also thought the ending became odd, and nothing like the Bruce we know. Even adding in gun use? Yeah...no.

Overall it's solid, different, weird, but not amazing. I'd say try it if want a different batman story. A 3 out of 5.
