Bad 👎 feels very rushed the whole way through. No depth to any of the characters. Cheesy acting to the point where it all seems sarcastic. Music throughout the film is so unfitting. The brutality of the crimes and devastion it would've caused was not portrayed. Seemed to glamorize at incorrect times. A very sad and educational story told in such a poor way, it's a real shame.
If it was someone's first film then fair but I'd avoid it if you're trying to understand the mentality of the killer.
