The Kingdom Hearts series got off to a poor start where combat is concerned. The first game has basically no depth to the battles; I'll agree with vivinox, it's a button-masher to the end. The second game slightly improved on it by adding quick-time events to the mix, but that wasn't enough. It wasn't until Birth By Sleep that they actually got it right, IMO. Blocking and parrying make the battles actually require reflexes, and the command deck and focus systems make them interesting.
Then again, I even preferred Chain of Memories to anything else pre-BbS. It actually required you to pay attention to what you were doing, a concept that most players seem to have struggled with. It was a bit clunky, but still a good deal deeper than just spamming attacks against regular enemires or whatever magic a boss is weak to.
