This one is weird; I played the turn-based RPG Harry Potter games for GBC, but thought they only did the first two in that style. Turns out, while Harry Potter 1, 2, and 4 on GBA are action adventure games, the 3rd one takes over the turn based style of the GBC games. The RPG combat here isn't half bad, they have this weird Golden Sun knockoff effect in the background which almost works, but doesn't stick the landing. Where this game fails is that the plot makes absolutely no sense. They picked the most random shit to turn into dungeons, such as going into Snape's back office or the basement of the bar in London. If you played the game before seeing the book/movie, you would have zero idea what was going on.
