OK, let me try to sum this up.

First of all I'd like to point out that this is not necessarily a bad movie, it will keep you entertained. You got a decent plot (yet fairly predictive), you got humor, and you got somewhat interesting characters.

HOWEVER, what you got most of is CGI, CGI and... CGI. I grew up with the Harry Potter movies and every time a new one came out I was always excited to see what new cool stuff they might of added with the latest technology.

These days you can animate almost anything and therefor some of that magic (no pun intended) you had before is now lost. I simply do not get impressed by the "fanastic beasts", I only see a blob of CGI that I can't relate to, they do not feel like a part of the real world, and there is just so many of them that after a while they end up giving me a headache.

During one part of the movie I ended up wondering if I'm not in fact watching The Avengers or X-Men. There's also one scene that reminded me very much of a particular scene from Star Wars, (You'll get it).

Do I recommend this movie? Well if you don't mind the things I just mentioned, you might like it.
