I said HBP because it skipped over the main plot.
In the HBP book, they focus mainly on Voldemort's memory, which is crucial to the overall plot of Deathly Hallows.
In the HBP movie, they only introduce us to 2 of the 7 Voldemort memories, and instead focus so much on romance and things that are irrelevant to the main plot. In addition, they added dumb things that weren't even in canon, like Cormac-liking-Hermione-from-the-start and the burning of the Burrow. The HBP movie is such a mess.
The HBP movie didn't feel like a Harry Potter movie, it felt so much like a romcom.
