This is my first review, not will give any spoiler, only what you need to know about it.
I decided to do a Bleach's review, because this manga, make me get into the anime/manga world, so I have a special affection to this, even not be one of my favorites anime/manga, this will always have a special space, for my childhood.
Bleach is a tradicional shounen, was started in the "shounens times", is about shinigami and hollows. The shinigamis are like "police offices", and hollows are the "serial killers", so the shinigamis have to take care of the real world, for hollow don't hurt people and stuff like that, and to control the world, for people don't discover this " other world". I like this kind of stuff, that you can't prove 100% sure that is all fantasy, that may can this true in the real world, make you think what is after the death.
I never liked so much fillers, but those from Bleach I find really great, my favorites, because is an whole arc, with plot, one saga story other filler, to balanced, not be random and in the middle of a main arc., this only until the arrancars saga, that they start to put fillers arcs in the middle of the main arc, and this arc is in 4 parts.
The problem with the serie, is that they use to repeated the combat moves a lot, and you become a little bored of combats. The good is that ins't forced moments, like someone bieng so strong only because they said it, forced a scene only to prove the non-useless of someone and the humor to forced. Have funny moments, and action moments, scary ones, all in the right time.
The story is divided in these arcs, I'm considered all, the manga and anime(fillers):

1- Shinigami substitute;
2- Soul Society;
3- Bounts(filler);
4- Arrancars, part 1;
5- Captain Amagai Shuusuke(filler);
6- Arrancars, part 2, Wekomundo;
7- The past(only the two last episodes are fillers);
8- Arrancars, part 3, Karakura;
9- The Zanpakutou tales;
10- Arrancars part 4, the fall;
11- The invasion army of the 13 divisions(filler);
12- Fullbrings;
13- The bloody war of a thousand years(manga, last).
