If you asked me if Beyblade was a "Masterpiece" I would say in my eyes yes.
However, if you asked me exactly WHY I liked Beyblade I wouldn't have an answer.
Beyblade is not that great of an anime from an adult or late teens point of view. But, if you grew up on Beyblade like me then no matter how bad it might actually be you might find yourself loving it.
I thought the characters were wonderful, I liked all of them except Doji. I was really into the story, especially when Ryuga came in.
In my opinion, I think Beyblade is a wonderful series and would
recommend it to anyone who asked.
However I can understand why people would not like it or give it a low rating.
So if you want to watch it, then it depends really. If you like shows for kids then go for it and if you wanna watch it for enjoyment and stuff go for it!
However if you are very picky about your anime then this might not be for you.
