After playing and owning all the Potter games, I would have had thought that this game would have had complimented the ending to such a great story. Myself, like so many other fans were greatly disappointed by HPDH Part 1 and hopedfor a better 2nd part.
Overall it is a massive improvement to Part 1. Movements don't seem as robotics and the use of the zoom function creates an illusion of a shooting game. There is no longer a need to pause the game to choose a spell and Protego no longer lasts forever.
Storywise it starts well and in the battle it creates an opportunity to play as other characters like Hermione, Ron and Professor McGonagal.
However, there has been a drop in the quality of graphics and the whole game can be played through in 4 hours. It certainly felt like it was rushed.
Honest opinion, do you remember the old RPG style Harry Potter games with the free roam option? I'm just going to pretend that HP and the Half Blood Prince was the last game in the series. At the current price on the truest Potter fans would buy it.
