I really liked Irukas voice since it was exactly how I imagined it in the dub. Naruto's voice sometimes strays off and doesn't make a good angry voice like the Japanese voice. I LOVE Shikamarus voice since it sounds pretty cool and it fits him. Kakashi's voice i thought just didnt fit him since he makes himself so..... dull talking in one tone all the time. lol thats what i think anyways.
