Eurogamer's Dan Whitehead write's "LEGO Harry Potter is enormous, which is no mean feat given that the title character is two centimetres tall. And plastic.
By the time I finished the sizeable story mode, encompassing the first four years of Harry's life at Hogwarts, I'd put more hours on the game clock than most "adult" action games demand, yet I was still at just over 45 per cent completion. I'd not completed any of the Hogwarts crests hidden in each of the levels. I'd unlocked a fraction of the game's 160-plus characters. I'd found only six of the secret red power bricks, rescued a mere 20 of the 50 imperilled students and earned less than half of the golden bricks which add up to unlock more bonus levels."
