The show overuses each joke. However this is just my personal opinion. People with different taste in anime might like this.
Personally i feel that the main cast and is simply a ripoff of other good shounen anime like naruto, bleach etc. For example loke seems to have an uncanny resemblance to ichigo from bleach.
The main character also seems to have the typical belief of never giving up and not betraying his friends like other shonen protagonists.
Overall the show seems really cliched.
