Lego Harry Poter follows the great formula of the previous games though the numerous glitches ruin it (with a good system you can manage to avoid all the glitches but the most common). It is heartbreaking to reach 98.8% and find out that you can not do the final level because the last gold brick cannot be retrieved. For this unfortunately I cannot rate this game what it truely deserves if the creators had actually done their jobs properly.
