The entire anime was really good however season 1 just stood out more because of its comedy and its humor but when the tournament started that's when the fights started to get good. Unfortunately the ending of season 1 was very confusing but except from that is was the best season out of the 3.
Season 2 and 3 however were a let down. It didn't have the excitement and thrill season 1 had it seemed like it kept repeating itself and there was no real focus on the main story line.
He shouldn't have gone back to keeping his emotions sealed but it was a really good anime at the end.
Highly recommended.
