No offense to anyone, but I'm not that into the Harry Potter movies. The books were excellent but the movies were...erm...not so much. Half of the fifth movie is the DA and the other half is the last part, at the...well I won't spoil it for you. So yeah, in my opinion this movie wasn't that great at all. :/
I had previously read the Percy Jackson series and wanted to check out the second series that Mr. Riordan had written after completing those books. To be honest, it isn't as good as the original series, because the friends--Grover, Annabeth, Percy, and Tyson--aren't together...but I won't spoil it for you.
Favorite book of the series! Absolutely love it! It is slightly depressing, and I won't spoil it for you, but let's just say you'll most likely cry after the last chapter. This is the pivot point of when the series gets more interesting.
