This Potter game plummets.
Harry Potter and the Order of the Phoneix has a merely passable storyline, but once again, that really does not have anything to do with the game. Everything to do with this Fantasy Action Adventure platformer is complete trash. From the character animation to the incoherent gameplay, the game really is made out to be lousy. Hogwarts may look nice, but it is a small good quality holding up the rest of the game.
So in a whole, Harry Potter and the Order of the Phoenix is a boring and tedious platformer with more holes than a kitchen sponge. Bad backround graphics, lousy gameplay, and annoying characters make the game.
As Harry himself has said in the films "I shouldn't have to be going through this, I really shouldn't". Yeah, that basically sums it up. You really shouldn't have to go through this game.
