In my opinion, this game is oustandingly brilliant! The graphics can't be beaten, and I think that the game follows the book and the film very well! Especially as the game goes on. Also, there are loads of spells to use once you've unlocked them, which are really fun to use against 'Snatchers' and 'Death Eaters'. I think that the game moves quickly, thanks to the 'Four Points' spell, which helps you know where to go.
The game is challenging, but do-able, which gives you a real sense of satisfaction when you complete a level.
The game is also good thanks to being in different places, other than Hogwarts, and that potions can be used against enemies.
I think that the vary of challenges you complete is great, some are similiar, but most are different. The similarity comes in when you are defeating someone again-but thats great fun anyway!
I think that this game is great, and a must have for any Harry Potter fan. I also think that it is definately worth a look for those people who aren't fans-it's that good!!
