Flow motion is a cool concept in theory, but the problem with it is that flowmotion attacks are mindless in execution and centralizing to the game's combat. This is made infuriating by how long these attacks last and how enemies often don't flinch when hit which can get you killed, even worse is when the camera goes wack and you can't grasp your positioning properly. The summon mechanic is super lame in that it functions to either be worthless or trivialize encounters in dull ways.
