Firstly, I'm not disagreeing with you if the direction intended for characters like Tidus to sound annoying. The quality of how it sounds to me is based on my personal preference and it's my belief that it can sound better than it is now. If one were to compare Masakazu Morita's take on Tidus, such as in the scene in being angry with Auron, the difference between how he does it and James Arnold Taylor isn't just how each actor chose to act or how the director wanted them to sound. If there's a way to increase the quality in making "annoying" scenes with the acting and the direction, then it should be aspired to and not just have to settle for less.
