Being a potter nerd I liked it but did have a few issues with it.
The one major one, other than the credence reveal (which felt really pushed) was how Queenie & Jacob were introduced, it was almost comical and I felt it could have been done better.
In the first movie we kind of guessed the obliviate spell was going wear off and they were going to be together again but I would have liked something like Queenie lifts the spell by using some ancient dark magic and has to run off to england with Jacob to hide from the authorities, something with a dark kind of twist to add more colour to her character, she's a nice girl but she's prepared to do whatever it takes to protect the ones she loves, I did though love how her character transforms in the end.
