I think anyone trying to rate this fan movie has to face a big question: should I consider the budget?
If the answer is yes, these guys only had a really small amount of money (around 15000 euro) so this is a good if not a great result, otherwise this is not a good movie and it can't be compared with a professional movie.
Another important problem is the plot, it's not that bad but it's quite trivial and the behavior of the characters -one in particular- is not realistic, he/she had many better ways to achieve the same result faster, it was probably written in that way just to impress the viewer.
There are also a few things that don't go well with the canon material but they genuinely tried to stay as canon as possible, The Cursed Child was worse on that aspect.
I suggest HP fans to watch it, there are also nice dialogues and scenes and overall it's a good and enjoyable effort.
