I only bought this set because it was discounted to under $3. But I've got to say, the Dobby minifigure isn't bad. And I like the sock plate piece. Otherwise the set ain't great shakes. The Harry figure isn't anything special, although I like Malfoy's alternate face / death eater mask on the other side of his head.
The odd thing though, is that the archway is designed so you can send Malfoy flying away by thumping him with a cleverly hidden stick.
