I cried when Claudia died. Did anyone else? Is it is kinda weird?

No, I got teared up too.

I didn't but I bett countless readers have.

There's nothing weird atau wrong with it. Fiction mirrors real life and thus characters may live to the reader, and Claudia is a very tragic character.

I just didn't get that fond of her.

i didn't cry.. but i certainly felt sorry for her.. too bad she was too young when she was made.. too young to defend herself.. too young to survive on her own..
imagine a grown up woman in a 5 tahun old body.. it's tragic..

I didn't cry because personally I thought Claudia was extremly ungreatful to Lestat and Louis, I also thought that she used them both in the end

I don't think its weird. If anda loved the girl

no
