Does anyone share my opinion that Harry Potter 4 5 and 6 sucked?

i mean the first 3 were good (HP 1 - the best, HP 2 - second best and HP - third best) but since then it seems like the movies were so poorly made, i was especially vexed by the duel between Voldemort and Dumbledore ( HP 5) - so hopelessly mundane. i mean in the book it was so chilling and awesome.
