The concept by Nolan is there, but at certain points he tried to do too much, and it made the story so much more complicated to follow.
Other than that, great movie with a anticlimactic ending
In a dark and overly sexual way, the half blood prince felt very different compared to other potter movies. I don’t know why, but something was off. That difference tho made me like the movie compared to the others besides the goblet.
P.S. - draco’s drip compared to everyone else is astonishing
