To each their taste, but I guess you're not familiar with Anbe Masahiro.
Yes it's light hearted and most of the comic sense is pretty japanese and thus might not hit westerners the same, it just means it's not made for you.
Also if he keeps the same formula as the 2 bangers he's done since 2007, we're headed towards 300-400 chapters over a few years bud, so of course the characters won't get developped much in the 10 introductory ones.
Overall you have quite the childlike behaviour, keep it up man, makes your opinions so much more serious.
