We had the drama behind the Minister Magic and relations with the Muggle government. We had the quite humorous interactions between Dumbledore and the Dursleys. We had the whole memory of Voldemort’s family - really quite crucial to the seventh book - and the memories of Voldemort finding the other Hogwarts founder items to use as Horcruxes. We had Bill and Fleur’s relationship. We had Tonks’s depression and patronus change, which led to Tonks and Remus’s relationship. We had lots of interaction and conflict between Harry’s house elves. We have Snape’s constant suspicion of Harry. We have the complications with Madame Rosmerta. And we had so much in the end - Harry being trapped under the Invisibility Cloak during Dumbledore’s death, an entire battle at Hogwarts, and Dumbledore’s elaborate and meaningful funeral.
A good list of the missing content in the Half-Blood Prince movie.
