Lego Harry Potter: Years 1-4

I wouldn't say I'm a huge harry potter fan but I loved the first movie as a kid when I saw it on my birthday with friends. I've always liked the Slytherin house and that's like a childhood memory for me. Harry potter 1 and 4 has the best characters in my personal opinion. I even remember collecting the lego sets from the first movie as a young boy and I still own the lego set of the final battle when Harry and Quirrell need to show down for one last battle. Lately I have been collecting Slytherin product and not because I'm a harry potter fan but because I enjoy some of it and I guess it's fair to say I'm a Slytherin fan.
