Spoiler warnings (however as not much happens there is not much to spoil)
I am a huge fan of this world, loved the first two movies though the second one didnt quite live up to the first. This movie however is the worst i've watched in a while, I spent the whole movie waiting for something to happen, anything to happen and it just didn't. There were so many moments where you thought something would begin and it just wandered off. The cgi is amzing, though at times unnecessary, the mirror world dumbledore plays with in this movie is a clear rip off from marvels doctor strange and just isn't explained at all. Several parts that made little sense, a few parts they seem to have messed up (thinking about the number of suitcases that we should have ended up with and the number they actually ended up with) and characters that if they were removed would make no difference to the plot. Mads made an okay grindlwald, Jacob was a good charachter and some of the other characters were good, the story itself however was just dull.
We find out who creedence is, we break a necklace, Jacob finally gets to be happy, but that is it, perhaps I am biassed because I actually expected something interesting to happen however I will most certainly not bother watching this again.
