Eh, I've always hated how crappy the wizards are in Harry Potter. Weak spells reused over and over again. Plus every single time, it's all about Harry having "love and friendship" in his life. Love and friendship make a good wizard? Pff, what a joke. If Voldemort really wanted to kill Harry, he would have bought a damn gun.
I haven't read the books, but damn, this is getting old.
