I found part 2 better than 1.
However, the character exploration for new and old characters were missing. The emotional part and professional conduct was contradicting in many characters (especially Goldsteins, Lestranges and the co-conspirators of Grindelwald).
McGonagall wasnt covered enough, I mean no justice was done to the duration of the role as well as the screenplay. It was as if she was covered as a "pedastrian" from a long distance and from a side angle.
Timeline was not explained properly. The film was fast.
Magic, new creatrures, magical objects needed more explanation.
These two films were lesser than expectations.
