My husband and I are AFOL and I must say, this is my all time second favorite Lego set next to the Hobbit house with the round door. We only worked on it in the evenings. This house and its interior is SO detailed - there is a really nice piano, couch, beds with pillows even, etc. The bathroom is amazing with a toilet, shower, tub, sink, "mirror" and Maggie's crib is adorable. PLUS, unlike the building series with the cinema, green grocer, town hall, etc. THIS house opens up in the middle so you can SEE the interior. Lego has outdone themselves.
I have never liked the TV show because the kids sass their parents nor did I allow my children to watch it as they were growing up so I am not familiar with the characters. I almost didn't order this on that basis but I am glad we did get it. Expert level building and over 2,500 pieces. It sure was fun to put together and is a keeper. The mini-figures and brick colors are so different from other sets - to reflect the cartoon nature of the Simpsons. Five Stars!
