I still really wish they'd focused more on the flashbacks to Voldemort's past in #6. They also dealt very poorly with the Harry/Ginny relationship throughout all the films (the last two are no exception in this), mainly in cutting their conversation after Dumbledore's death (which I felt was very important character-wise).

Other than that, Yates' entries (5, 6, and both of 7) were easily my favorites of the series, followed closely by 3. (The first two are pretty good, but 4 just blows chunks until the last half hour.)
