Plot made no sense, the stakes made no sense, the character motivations and choices were poorly plotted and made no sense, some acting was good but there were some howlers too, and the ending, lacking closure or the actual dual between Dumbledore and Grindlewald alluded to in Hallows, was a soggy fizzle, far from a bang. Overall...this magic world seems to gets weaker and less coherent the more of it we see.
