We saw this in IMAX and, while it was a novelty, I don't think it was worth the extra money. On the plus side, I won brownie points from the big Harry Potter fan in the family. A good continuation of the Harry Potter tale and it was enjoyable to see the same actors maturing in their characters - after all they couldn't stay teenagers forever at Hogwart's. I'm with the fan who would have liked the entire ending in one long film instead of broken into 2 separate money makers.
