I'll probably be in the minority here, but one of my favourite CBMs in the last few years was Punisher War Zone. It was more faithful to the character than any X-Men or Spider-Man movie to date. It was unapologetic, ultra-violent action from the get-go. I loved it.
I agree. That movie was great and very underrated. However, it's another example of an R rated superhero movie that flopped.
