Harry Potter

I have heard of this series called Harry Potter.  I have heard great praise of this series and decided to take a turn reading it.  I thought the book quite interesting.  But I did find some glaring problems with the books. For instance why were James or Lily they’re own secret keepers. Also how did the twin brothers fred and george not see the rat man on the marauder's map? And why do the wizards not use the truth potion it court? It would make sense. Also It's my understanding that portkeys only go one way but in the goblet of fire it goes both ways.  Also I fear there is much judgement within the houses. I feel like hufflepuffs are treated as idiots, raven claws are snobs, gryffindors aren't all amazing, and slytherins are not exactly evil.  But despite the flaws I found the book quite enjoyable. Though it's not exactly my style my sister kitty would very much enjoy it I feel.
