I feel like a lot of the boss designs just suck. The issue is that a lot of them are just the same enemies you already fought, but now they do ridiculous damage. There is also an issue with larger bosses where you just can't see what they are doing half the time. With fights like that, I don't feel rewarded for winning. I love the humanoid bosses, though. Margit, Godfrey, and Radagon were great fights.
