As a Lego professional builder, I found it this set lacked quality bricks, proper design, and may have been rushed. The first thing that I noticed was the brick quality in bag 2 and 3, and it carried through to all the bags. I purchased the set to do a diorama at a movie theater by request, the set ended up getting a complete redesign and color change to dark red because the brown bricks were of such poor quality. Also the playability of the set I felt was rushed and could have been done much nicer. The best feature of this set was the mini figures. The lack of detailed sections was disappointing. The one build section that was close to being up to par with a set this big to me was the laundry area, that was the nicest part of this build. The "snow" on the roof, well, it was sub-par at best. This set should have been the best of the series, but I think the penguins car was the most impressive as far as build technic goes. Even with redesigning and switching colored, it only took 4 hours to build.
