Fantastic Beasts 2

Maybe it is because I'm not a reader of the books(i read the original Potters) but I don't get all the hate from both fans and critics for Fantastic Beasts 2.  Sure it may not have the pure beauty of the Potter flicks but it is not as loaded,  as was the previous Beasts flick.  I liked the darker tones with Grindelwald and the screwball humor of Newt. My only complaint is the cgi of the magic demon panthers.
