I would have loved this as a kid. Heck, I would now. The only problem is that I am very bad at building things and this thing has over 3,900 pieces. It would take me about 6 or 7 years to finish. That includes the time I'd have to wait for some small pieces to work their way through my dog's intestinal tract. You could probably build a real Death Star in the time it would take me to build this thing. I am not very good with my hands.
This is way cooler than any LEGOs we had as a kid. I don't remember anything tied to movies or TV shows. They were only generic cars, planes, and people. Again, not that I was able to build any of these things, I only remember what my brother built.
Anyway, go buy it, and let me know how long it takes to build. Start saving some money , though. It costs 400 big ones. More pictures over at the Lego store. Go. Buy. Now.
