The flaw they say are the filler episodes and I agree but personally I found some sagas of filler episodes very beautiful for example the saga of the alternative history of the Zanpackutō and the Saga of the invading army of the Thirteen Brigades.
I found the characters very interesting starting from the protagonist Ichigo Kurosaki who seems cold and detached and who likes to get into fights, but in reality he is good and is always ready to help his friends if they are in difficulty. There are also other very interesting characters such as Renji Abarai, Zaraki Kempachi, Kira Izuru and others, each with their strengths and weaknesses. And they all have their own personal evolution which I really liked.
I liked the story in general, some moments more than others, I found it boring at the beginning but then as I progressed I liked it a lot, above all the fights are well done and some had me very excited, I also found some of the protagonist's transformations fantastic.
In conclusion I recommend you see it because it is well made and is funny in some moments and there are also some nice reflections.
