this was my first anime so i may have been a little bias, also unlike a lot of people i didnt skip the filler arcs that are in-between the major arcs. despite this it was a very good anime i see how it got so popular but of the big 4 (yes i am one of those people who count fairy tail as the new entry to the previous big 3 bleach one piece and naruto ) it is my least favourite .
i loved the fight scenes and as the budget increased so did the quality so that why i loved it so. my favourite character has to be kenpachi he is just pure awesomeness.
despite some of the filler arcs to be quite amusing i recommend watching the main arcs ( however if you want to watch the filler arcs the wait till the main arc is oer and go back and watch it which is what i wished i had done)
