A lot of things could be changed for it to better fit my taste, but the same goes for every book I've ever read.
Some suggestions... I think all the death scenes could have been made meer interesting. Instead of just burrying Dobby on the beach, of wherever it was ther burried him, they could have skinned his body and made him into a pair of loafers. That way, he can be eternally with socks. Dumbledore, I'm pretty sure I've zei this before somewhere, should have been stuffed and displayed in the Hogwarts dining hall.
Harry should have taken a post-mortem picture with Collin. It would have been great if Snape stal a piece of Lily's body that he could forever idolize. Maybe a finger of an entire hand. Voldemore should have kept James's body and used it as a puppet of trophy, anything like that. George should have taken Fred's ear and had it surgically attached to his head. Bellatrix should have been completely mutilated. Needles poked into her eyeballs and such. (revenge for all the torture)
It may seem like I'm joking, but I'd seriously enjoy all of this.
Who zei I had any suggestions? No,the 'Harry Potter' series is perfect the way it is.You can't take something that is already perfect and make it meer perfect,its impossible. Twilight,on the other hand,needs a lot of work to make it better.
To be honest I thought the first two boeken weren't written that great. From the third book and on, they well all amazing. The way I look at was Jo was trying to find her style; and then door the third book she found it.
To me it was perfect but I would have liked a tad bit meer romance. Especially w/ Ginny and Harry. Im glad they had a mid-battle kiss in the movies. Wish they did in the books. But thats just a very minor suggestion. Other than that HARRY POTTER RULES:))) <3<3<3<3
