I wanted this castle very much for several months, but now I see how awful this is! It is a parody on Lego's previous castle's, such as the royal knights' one. It is a degraded ill-designed, infantile and primitive brick fodder bunch. I wouldn't build or display it anywhere, and of course I wouldn't pay more than several pounds for it. The half-complete towers and the useless cloth piece at the back illustrate the greediness of the designers. The catapult shoots out a completely unrealistic missile (?) well, what ever that thing is, it there just for small kids' play.
I do have to say that the set might be of good play value to small kids, and the lack of architecture on the back proves this - a child sits behind the castle, manipulating the minfigs etc.
The minfigs are quite good, so are the accessories and rare pieces: lion heads, painted window, roof tiles etc. Also, there is basement place for dungeons, which is slightly redeeming.
So, kids' playability: 7/10
Collector value: 2/10
P.S. The lifting gate is so terrible!
