Having enjoyed my first Lego (Indiana Jones), I wanted to attempt the adventure with Harry Potter. What a disappointment !! The game offers a digest of several films so much too messy and too short! The events keep coming far too quickly and without explanation. Anyway after 2 hours of play, I still do not understand the script and never went back in history. This opus Lego is intended only to fans of Harry Potter films that arrive alone to follow the scenario without much difficulty, at least I hope. In short, very very disappointed ... FYI, I play Lego games only in cooperation mode.
