Blegh... "And that's all I have to say about that" ( :| )
But seriously, I don't really like the Harry Potter series all too much. The series started strongly as a fantasy series for children. J.K. Rowling, unquestionably, is able to captivate the minds of her target audience: children. Her use of literary themes such as the importance of friendship, overcoming evil and father-figures, while cliche, do appeal to most. It's better to read happy endings, rather than endings where the bad guy comes out on top.
Despite this, J.K. Rowling, while still writing in the style of a children's author, moved away from childish themes. As Potter matured, so too did J.K. Rowling's target audience. While incorporating more mature themes, such as death, dark pasts, and the triumph of evil, Rowling still wrote her stories in the same style as her previous lighter ones. This blend of dark ideas and children-targeted writing caused for the formation of an awkward story which, while appealing, lacked a sense of satisfaction. This idea comes to full fruition in the epilogue of the final book.
The cliche ending in which the protagonist dies, comes back to life, then defeats the villain is trumped by the even more cliche ending of everyone living happily ever after, marrying each other in a strange criss-cross of love.
"Hey, best bud! I banged your sister thrice+ times! I think I'ma name all dem love-childs after dead people."
The "happily-ever-after" ending is an ending commonly attributed to the childlike fantasy stories of the Disney variety. While I too love these endings, these endings don't seem appropriate, given the tone of the last few books. It seems as if this ending did not enhance the life of any of the main protagonists. Instead of learning something, or taking something profound away from all these near-death experiences, it seems much more as if they were just wiping the sweat from their brow thinking, "Thank god that bat-sh-t is over...".
While I can't deny that there is something behind J.K. Rowling's writing that keeps people of all ages coming for more, I fairly state that, with such a widespread demographic of readers, it is impossible for her to please everyone. Her attempt to cater to the entirety of her audience, incorporating dark themes within children's writing, created an awkwardly written novel which I, personally, don't enjoy.
I've never read Harry Potter 1-2 and 5-7...Let the flaming begin ( :| )
