Keep in mind that all the seven do have very different personalities. Jason is serious, Leo is joking, Frank is kind-hearted, Hazel is the innocent one (not knowing a lot about modern day stuff), Annabeth is the smart one, Piper is the emotional one, and Percy is kind of a Jack-of-all-Trades as he has a little bit of everything. However, because they have different personalities and they all have time to talk (the different Points of View in this series), it makes it more likely that someone won't like everyone in the seven. I mean I'm not a big fan of Jason because he makes cardboard look exciting. People don't like Piper because pretty much all she talks about is Jason. It is very hard to make every character likeable to every reader out there, but one bad character in seven (sometimes more than one) is a pretty good record in my opinion.
