Kovu is my LEAST favorite character in the whole LK series. There are reasons why.
Kovu reminds me of some annoying modern disney pop star with his manedo and his voice. It's weird how he is all, "I kill Simba, I am destined to do so because momma says so." Then when spends a less then a day with Kiara he's all, "She's so sweet, awesome, and great I have to reform my ways." in that instant. I get the film was short and it was most likely that kids were watching it, but the people that were making this film I don't think REALLY understood the point of the original Lion King.
When the film came out I was just neturual with Kovu. I just liked him because he just seemed to be a cool character and he was mainly Kiara's love interest, but because I am older and have compared the second film with the first, I see SO MANY differences.
Now probably the only reason why Kovu doesn't have as much depth to him as the movie tries to imply but fails to do so, (at least for me) because he is mainly Kiara's love interest.
I'm sorry if I have upset anyone with my opinion towards Kovu, I just don't like him...he just is a bland character to me. If this film had more time and the people actually tried to put a lot of depth to the film, like have more scenes with Nuka, Kovu, or Nala, I think more people would have liked it and I wouldn't have the three following characters so low in my list of favorite characters.
