As much as I love this game...

Each boss fight I have is the worst boss fight I have ever had in 40 years as a gamer. Now, before you Dark Souls people come in here twisting your nipples "oh that's easy compared to Dark Souls" it's not just about difficulty, it's about the design is f'n horrible. Crimson Nightmare was just the least fun boss fight I have ever had. Each battle is just an exercise is frustration at unblockable attacks and bosses teleporting all over the damned place.
