Recently there was also some critique on Bleach on here. I used to watch things like Naruto, Bleach, Fairy Tail, etc when I was young. I do really think you need to be quite young and naive and excited by dumb action in order to enjoy this type of anime (as I was back when I watched those). They are also very long, so for an adult with not that much time you would be much better off watching a bunch of shorter anime than to commit to such big one. And in my experience all those types of long running shounen have bad writing, massive plot holes, terrible romance, dragging out the plot, power creep, etc. Those shows are definitely overrated in my opinion.
