The main game was ok, but the Tintin & Haddock mode game was great. It could have been it's own 800pt XBLA/PSN game and it would have gotten great reviews.
I don't like replaying movies as a game (unless it's LEGO'fied), and that's what the main game does, but T&H is a crazy dream-sequence 2D platformy sidescroller with at least 5 hours of fun gameplay.
