The very same goes to the plot of Bleach: There are some very interesting storyparts, as well as many plotholes and odds in the story (For example take a look at Soul Society - I'll never get why people grow up and die in a place they came to after they died on earth ...).
The humour used in Bleach also has his ups and downs. Even though many jokes might not even scratch your lips, others will make you laugh hard enough to almost fall off your chair.
The show always reaches his top when Ichigo is about to fight seriously, since those fight scenes are usually pretty cool, even though they are mostly kinda overdone.
Bleach in general is a pretty enjoyable anime, especially the first few episodes are very entertaining and humorous. It's a shame it has some very boring story parts, many plotholes, many filler episodes and does not have much development in character relationships ... :(
