Based on the Movie allows alot of free roaming. Also the Endless day at the end allows you to complete side quests. Fights are chaotic, and some quests will drive you insane, but the only real flaw is the Camera view.
I was waiting for this game for awhile. When i got it in the mail I raced to my room put it in my 360 and enjoyed. I beat the game in one day it's very easy and repeative. It is actually very fun to run around Hogwarts. But after 1 week it gets very boring. You should rent it.
This is, by far, the best Harry Potter game to date. The graphics were good, Hogwarts was spectacular to look at, and the open ended feel of the game was nice. Casting spells was a bit different in regards to different movements by the right stick are what casts a spell rather than a button. Took a while to get the hang of, but once you've started leveling up, casting becomes easier and more powerful. My only complaint is that there could have been much more in the way of spell fighting and dueling, but when you did have to duel, it was very fun and entertaining. In the later Harry Potter's, there is more spell fighting than The Order had, so my hopes for this game in the future are bolstered immensely.
