I would like to start off with the fact that I read the book.
Did I enjoy it? Yes, but I didn't cry.For me the book was just cute,at some parts funny and I did enjoy it,I didn't love it as some people did BUT I did like it. I didn't cry at all though.
I liked the movie better to be honest, I didn't cry but I almost did at some parts.

[spoiler]There is, in the movie as well as the book, one part that I found really bizarre. The part in the Anne Frank house, it's supposed to honor the people that died and they just start making out! That is wrong on SO MANY LEVELS. [/spoiler]

It was a good movie, no lie and I would watch it again but one thing that was completely unrealistic was the way they speak. I do understand that it was written by an adult but it's supposed to be in the mind of a teenager, not Shakespeare. They use all these words that no teenager these days would use, for example in the trailer of the movie Gus says:

_...I know that love is just a shout into the void, and that oblivion is inevitable..._

NO TEENAGER WOULD SAY THIS!
