Here is my review on latest LEGO Harry Potter GWP 40577 Hogwarts Grand Staircase:
THE GOOD:
Interesting building exp.
Great desktop display sets.
Very well done on the rotating stairs.
THE NOT SO GOOD:
Wish some improvements in terms of design the the roof/top surface.
Need specific sets from the Hogwarts Castle series to make this set looks nice.
Very hard to get this.
Overall, I like it and I do think it is a very good GWP. Looks good, interesting build experience and fairly good volume. It's great the stair can change orientation. While not a fan of sticker, I also did find the stickers make sense in this set. Could be better if including one more minifigs. Having said that, the roof/top of this build are the weakest in my opinion. Also this set only connects well if you have a 2 storeys set from the Hogwarts Castle series. but then the most important improvement I wish Lego did , was to have this more widely available, with supply chain delay, sometimes it is hard to find items to buy to reach the high threshold for this kind of rewards. And more importantly the Harry Portter GWP I missed last year are now at ridiculous price after market =(
